Excretion time from the body

On this page, you can take an alcohol test online and find out if you can drive, and if not, how long should it take for your blood alcohol level to be normal.

The test is based on a person's physiological data - gender and weight, types of alcoholic beverages and the time that has passed since drinking.

The program automatically calculates the amount of alcohol in drinks, how much a man or woman with a certain weight needs to make sure that the body can cope with alcohol, and according to the time that has passed since drinking - is it possible to drive already, or how much more time is needed, what If the breathalyzer showed the alcohol content is normal.

Why do you need to know the alcohol content before leaving?

It is difficult for a person after drinking strong drinks to determine whether he is really sober or not.

In addition, it is difficult to predict the readings of a breathalyzer, and most likely there will not be such a device at home. Depending on the amount and tolerance of alcohol by a particular person, his condition may be outwardly indistinguishable from sober.

If we do not take into account the state when intoxication is noticeable to the naked eye and a person looks sober, even a small amount of alcohol affects the ability to perceive information - the driver begins to lose measure, he overestimates himself and underestimates the traffic situation.

In addition, the reaction speed slows down in case of unforeseen situations. For example, 100 grams of pure alcohol slows down the reaction rate by 2-4 times. Therefore, even a small amount of alcohol makes the driver dangerous to others.

While driving, the following signs can give out a drunk person behind the wheel: sudden braking, overly self-confident or overly cautious movement, ignoring prohibitory signals, leaving traffic lights late, unnatural trajectories of movement - a combination of such signs can cause the car to stop for a subsequent check of the driver for sobriety.

During communication with the inspector - the smell of alcohol from the mouth, it is difficult for a person to express himself, the pupils do not react to light, a red face, or vice versa - pallor, inadequate condition, difficulty in movement and impaired coordination. One of the listed conditions is enough to receive an offer to be tested for alcohol content in the body.

Passing an alcohol test with breathalyzers

Alcohol testing can be done on site, with mobile devices and in the laboratory.

For a quick test that will allow you to immediately decide on the likelihood of the presence of alcohol in the blood, a breathalyzer is a device that determines the concentration of alcohol in the exhaled air of a person.

Breathalyzers are:

1. household, for individual self-control;
2. special, for more frequent use than household;
3. professional, designed for a large number of measurements per day.

Household ones can rarely be used in small businesses to make sure that an employee can be put behind the wheel. This tester is designed for infrequent use. Special ones are more often used at enterprises before the release of drivers on a flight or route, as well as at enterprises where work is carried out with increased danger.

Special testers in some countries are used by the traffic police, may have a certificate that they are a medical product. Such devices are designed for an average of 30-50 applications per day.

Professional breathalyzers are designed for multiple use throughout the day. These tests are most often used by the traffic police to determine the content of ppm in the body, they can be connected to a printer to print out the results of the analysis.

Special and professional testers are periodically verified and calibrated for accuracy

If the inspector offers you to take a test on a breathalyzer, you need to remember that you must first show the device itself and advise on how to pass the test correctly. Everyone can demand to show the license and certificate of the device.

Examination for alcohol content must take place at the place where the vehicle stops, the presence of two witnesses is a prerequisite. If the alcohol level is less than 0.2 ppm, then the driver is no longer detained. If more, then a protocol is drawn up where the test indicators are indicated.

Upon agreement with the indicators, the driver is released, and the protocol and other related documents are submitted to the court. If the person who was tested does not agree with the results, a second test is carried out in the laboratory (first-aid post).

The driver has the right to refuse to undergo a breathalyzer test, in which case the examination will take place in the laboratory.

Only a qualified doctor has the right to conduct an examination in a medical institution

The examination includes checking the pulse, pressure, pupil reaction to light, psychophysiological check. It is carried out twice, the second time - after 20 minutes after the first.

Biological samples are collected - blood, urine and saliva are taken in duplicate - one is used immediately for research, the second sample is stored for 90 days in case the driver during the trial wants to re-examine. The results of the survey are issued in triplicate - one for the driver, one for the inspector and one for the doctor.

If today you need to be driving, and the day before you drank alcohol, then you need to make sure that there is no alcohol left in the body. If the number of ppm cannot be checked with a breathalyzer before departure, we suggest using an online test. It does not require a store purchase, periodic calibrations and expiration dates.

Specify the minimum required parameters in the test, and the program will calculate the amount of ppm and how much more time alcohol needs to make your indicators in order.

The most accurate alcohol calculator in Russia (see instructions)

Instructions for using the alcohol calculator

Alcohol calculator site will be useful for you if you want to know:

• after what time you can get behind the wheel and drive a car after drinking alcohol;
• how much alcohol has entered the body;
• how much alcohol is contained in the blood and in the exhaled air;
• what degree of intoxication has been achieved;
• What are the consequences and how to deal with them.

For the calculator to make the correct calculation, follow the instructions:

1. Enter your gender and age. Gender affects the amount of alcohol that will be absorbed by the body, age affects the rate of alcohol elimination.
2. Enter your height and weight. These data also affect the amount of alcohol absorbed by the body.
3. Specify the strength and volume of drinks, up to 5 pieces. For calculation, it is allowed to use a strength in the range of 0.5 - 96% and a volume of 50-10000 ml. If you drank more than 10,000 ml of one drink, enter the remaining amount in the next field.
4. Specify whether you had a full or empty stomach at the time of drinking the first dose of alcohol, and click the "Calculate" button

Our alcohol calculator is fully suitable for use by drivers in 2019.

Alcohol Calculator Results

Maximum expected alcohol withdrawal time calculated based on your personal characteristics. It is this value that can be taken into account to determine the time when you can drive and drive a car. Minimum, average and maximum time - a general calculation without taking into account some parameters. These options can be ignored in most cases.

Exceptions:

• if you have a serious injury or illness, we recommend that you focus on the maximum time to remove alcohol;
• if during the removal of alcohol from the body you were engaged in heavy physical activity, then you can take the minimum time and add 15-25% to it;
• in people who regularly drink alcohol, the time to remove alcohol from the blood is less than in those who rarely drink. But, unfortunately, it is impossible to determine the exact time of alcohol withdrawal in this case without individual medical studies.

Note: Our alcohol calculator shows the time of complete elimination of alcohol from the blood and does not take into account the allowable rate of 0.3 ‰. Given the possible small error in the calculations of the calculator, we recommend that you focus on the total withdrawal time.

Used formulas for counting alcohol

The mathematical model underlying the site's alcohol calculator uses the generally accepted formula of the Swedish chemist Erik Widmark. It is this formula that forensic experts around the world use to determine the amount of alcohol in the human body at a particular point in time:

where: BAC- concentration of alcohol (g/l); t- time elapsed since use; A- mass of pure ethanol in the drink (g); r- Widmark factor; W- body weight (kg); k- alcohol absorption rate constant (h -1); b- alcohol elimination rate ((g/l)/h);

To calculate the coefficients, the works of Seidl (S. Seidl, University of Vienna) and Forrest (Alexander Robert W. Forrest, University of Sheffield) were used.

Why our calculator is the most accurate

When developing our alcohol calculator, we studied and took into account all the factors and methods used in the world of forensic medicine. Our calculator was developed in 2010 and for a long time was available only to a limited circle of people in the form of a specialized program in the Java programming language. During this time, the accuracy of the calculations has been repeatedly confirmed in practice.

Comparison with other breathalyzers online

On the Internet you can find many different alcohol calculators And breathalyzers online, but most of them use only the simplest formulas and average (simplified) coefficients. We managed to find only 2 real full-fledged alcohol calculators in Russian, but even they take into account fewer factors than our calculator.

When can you drive after drinking alcohol?

It is very important to remember that the absence of alcohol in the blood does not in itself give you the right to drive a car.

According to paragraph 2.7 of the traffic rules of the Russian Federation:

2.7. The driver is prohibited from:
drive a vehicle in a state of intoxication(alcoholic, narcotic or otherwise), under the influence of drugs that impair reaction and attention, in a sick or tired state endangering traffic safety;
transfer control of a vehicle to persons in a state of intoxication, under the influence of drugs, in a sick or tired state, as well as to persons who do not have a driver's license for the right to drive a vehicle of the corresponding category or subcategory, except for cases of driving instruction in accordance with section 21 of the Rules;

The driver is not allowed to drive the car in a tired or sick state. A strong and moderate hangover is just a painful condition, and it is strictly forbidden to drive. If you are sick or tired during an accident, you will be found guilty. Driving in this condition is dangerous for the driver, passengers and other road users.

Therefore, do not drive while hungover, even if the alcohol is completely eliminated from the body.

Stages of alcohol intoxication

Less than 0.3 ‰ - no influence of alcohol

There are no effects, the behavior is normal. The presence of alcohol in the blood can only be determined with the help of special tests.

From 0.3 to 0.5 ‰ - insignificant influence of alcohol

It is difficult for a person to concentrate, the following effects are possible: talkativeness, a feeling of joy, relaxation, mild euphoria.

From 0.5 to 1.5 ‰ - slight intoxication

Sensations are dulled, disinhibition and extraversion are possible. Violations are possible: reasoning, depth of perception, peripheral vision.

From 1.5 to 2.5 ‰ - moderate intoxication

A person is characterized by: variability of emotions, over-expressiveness, strong anger or sadness, fury, decreased libido. Reflexes and basic motor skills are impaired, reaction time is reduced. There is a possibility of temporary alcohol poisoning.

From 2.5 to 3.0 ‰ - severe intoxication

The following changes in behavior are possible: stupor, dullness of sensations, loss of the ability to understand. There is a possibility of loss of consciousness. Severe dysmotility and memory loss may also be present.

From 3.0 to 5.0 ‰ - severe alcohol poisoning, death may occur

Severe depression of the functions of the central nervous system, loss of consciousness, coma and death are possible. There may be disturbances in the control of urination, the functions of the respiratory system and a complete loss of balance.

More than 5.0 ‰ - fatal poisoning.

High risk of alcoholic coma, loss of consciousness, there is a possibility of death.

How alcohol is considered in the courts

When conducting research, forensic experts use the same formulas and guidelines that were used in the development of our alcohol calculator. However, when conducting research for courts, forensic scientists use coefficients that are more beneficial to the defendant. If it is necessary to determine the degree of alcohol intoxication in an accident that occurred a few hours before blood sampling from the accused, then the minimum coefficient of alcohol removal from the body is applied: 0.10 ‰/hour. If it is necessary to show that at the time of the crime the defendant was in a state of insanity, then the maximum coefficient is used in the calculation: 0.20 ‰/hour. Unfortunately, forensic experts in Russia do not always use exact formulas, but often use the average values ​​of the coefficients from the guidelines.

Alcohol Calculator Discussion

The international version of our alcohol calculator is available here: BAC Calculator. We would love to hear your opinion about our alcohol calculator. You can leave a comment at

Passed in 2013, the law on permissible ppm in a driver was perceived by some as an opportunity to drink and drive in small quantities. But this innovation, on the contrary, as it turned out, completely takes away the opportunity to drive while not sober. In 2018 and 2019, the bastards tightened the legislation, so drivers are advised to use breathalyzers, even after an "evening" glass of beer.

On the other hand, acceptable blood alcohol content allows people to safely consume their favorite products containing a minimum amount of ethanol or take alcohol-based medications.

The problem that has arisen for motorists has several solutions, for example:

• checking blood for alcohol content;
• testing of exhaled carbon dioxide and its analysis with a special breathalyzer;
• The cheapest way to determine the alcohol content is online calculators, one of which is presented on this page.

It is also impossible to get around the topic of removing alcohol from the blood, the ethanol content in different drinks, as well as the degree of intoxication - these issues are briefly discussed in the material.

Simple Calculator Algorithm

The online breathalyzer presented above was developed in close collaboration with practicing narcologists and forensic doctors based on confirmed data and approved methods. Therefore, Internet users have a unique opportunity to calculate all possible options for consuming alcoholic beverages on a convenient, practical calculator.

The result - after getting acquainted with the details of use and application, the alcohol calculator will become an accessible tool for the driver for a sober assessment of the situation and safe driving in any traffic situation.

Note:

The most important advantage of an online breathalyzer is accessibility. To use the alcohol calculator for the driver 2018-2019, you do not need to be imbued with complex instructions. The convenient interface of the page allows you to find out online how much a particular driver needs to rest after taking a certain type of alcohol, with a known volume. A person just needs to go to the site, fill in the appropriate fields on the calculator:

1. Specify gender. The rate of elimination of alcohol from the body in women is lower than in men. This fact is confirmed by scientific research, observations and is simply explained - the body of men contains more digestive enzymes. Consequently, any food and alcoholic beverages are absorbed, processed, and excreted faster;
2. Body mass. Again, it's all about physiology. A big man needs a lot of food. The process of digestion is more active, metabolism is faster. Consequently, the owner of a smaller body weight can get behind the wheel later than a large motorist. The greater the difference between them in kilograms, the more significantly the time interval for removing alcohol from the blood on the breathalyzer will differ;
3. Growth. In tall people, the body normalizes faster after alcohol intoxication than in short ones. The explanation is simple - in a tall, thin person, the body requires more nutrients. Food, drink from the stomach, the digestive system tries to deliver as quickly as possible to the starving tissues;
4. The strength of the drink and the volume of the drink significantly affect the state of the drinker. For example, let's take a strong man with perfect health, then he can drink a small glass of beer 0.33 liters and safely drive. But, if the driver drinks the same volume of alcoholic beverages, then the alcohol content in the blood will not allow him to safely drive the car for at least the next 10 hours.

As you can see, in addition to human physiology, the degree of intoxication is affected by the type of alcoholic beverage. Therefore, it is extremely important to be aware of what you are going to drink, and what consequences this may lead to.

Alcohol content in drinks for entering data into an online breathalyzer

In order to properly use this breathalyzer online accurate 2018-2019, we offer motorists a summary table for removing alcohol from the blood. Here are popular 0.5 liter alcoholic drinks and how long they can keep the average healthy male motorist 180 cm tall, weighing 80 kg from driving. According to the table, it is convenient for a person to determine which drink he should drink in order to be ready to drive a car after a certain period of time.

Table 1 - The average time to remove alcohol from the body

Note:

The given calculator data make it clear that if the driver needs to leave in the near future, then you can drink no more than half a liter of alcohol with a strength lower than wine. But it should be noted that the online breathalyzer gives the average value of removing alcohol from the body. That is, for a person who is absolutely healthy, well-eaten, strong, the results will be lower. Well, if the driver is tired, hungry, exhausted by a chronic disease, instead of resting he prefers to drink a bottle of vodka, it will take a day to recover.

Dangerous indications of ppm content on an alcohol calculator

The best characterizes the state of people who have drunk a certain amount of alcohol, the concept is the degree of intoxication. This parameter is determined according to a manual that has been proving its competence since 1974, developed back in the USSR by the Ministry of Health for forensic diagnosis of ethyl alcohol poisoning.

Consideration should be given to the fact that alcohol is present in many foods from the daily diet. Only a blood test can give a complete picture of the condition of a drunk person. There is a single parameter called ppm. It shows the content of one thousandth of a percent of alcohol in a person's blood. Summing up, we have figures and methodological explanations, which we summarize for convenience in a table.

Table 2 - Characteristics of the degree of intoxication

Life-safe ppm on an online breathalyzer

With this calculator, you can find out your rate of alcohol consumption. The content of alcohol in the blood, from the alcohol consumed as a result, should not exceed 1.5 ppm. That is, if a man of athletic build, 180 cm tall, weighing 80 kg, is going to drink vodka at an event, he must be aware that after drinking more than 0.3 liters, the body will receive more than 1.5 ppm into the blood. Thus, a person will go into the ΙΙ degree of alcohol intoxication:

• Slight clouding of consciousness;
• Violation of coordination of movements;
• Incomprehensible to others muttering;
• slow response
• vision distortion;
• The period of removing alcohol from the blood is at least 10 hours.

There is no need to talk about driving in this state. It is worth adding that the loss of self-control due to clouding of consciousness usually leads to additional alcohol abuse. As a result, a person runs the risk of moving to the next stages of alcohol intoxication, which are already dangerous to health and life.

Permissible standards for the driver

In all countries, different norms for the permissible concentration of ethanol in the blood are established. Most likely, this trend is associated with the vital, moral foundations, traditions that have developed among specific social groups. It depends on the culture and style of driving, traffic intensity. The French with an established culture of production and consumption of alcoholic beverages are allowed 0.8 ppm in the blood. Hotter and more temperamental Spaniards, Italians, the limit was limited at around 0.5. The Scandinavians also joined them. The countries of North America, Canada and the USA, which differ in their customs and freedoms, allow driving a car with an alcohol content of no more than 0.8 in the blood, but on condition that the driver is over 21 years old.

Russian standard by law

In Russia, until recently, any ppm driving was banned. But, the exact breathalyzer that appeared made it clear that it is difficult to achieve absolute zero. There was also a question about the expediency of a zero indicator, if the presence in the blood of less than 0.3 ‰ of ethanol alcohol has no effect on the driver. Therefore, for 2018, as well as for 2019, Russia has a limit of 0.35 ‰. The Russian limit is lower than in most European countries. There, 0.5 or 0.8 ppm is generally allowed.

A stricter limit is due to the fact that our legislators are against the consumption of alcohol while driving in any quantity and quality. The existing allowable dose is designed to smooth out the possible error of breathalyzers, take into account possible cases when drivers take food, medicines containing a small part of the ethanol content.

Additional protective measures

Before sitting at the festive table, the driver is advised to study the alcohol calculator on the breathalyzer website online. Conclude how much you can drink and how long after that it is allowed to drive. But in order to protect yourself from trouble with the traffic police, it is better to purchase a portable breathalyzer. If the driver often drives and has close contact with ethanol-containing products, it becomes necessary to accurately control ppm in the body.

Compared to possible fines of 30,000 rubles plus deprivation of rights up to 2 years, the cost of a portable breathalyzer is much lower. Keep in mind that a repeated similar violation of the rules of the road is punished even more severely, from an administrative offense, goes into the category of criminal. Therefore, the fine grows to 300,000 rubles, the rights are deprived for 3 years, and they can be imprisoned for 2 years.

Note:

Portable breathalyzers are designed to protect disciplined drivers from unpleasant surprises on the road. Who is warned is protected. Bon voyage and neither a nail nor a wand.

Alcohol has long been a part of human life. It is difficult to imagine solemn feasts without fine cognacs and fragrant wines. But this, as they say, is only one side of the coin. Often, festive chic ends, if not in tragedy, then in trouble with police inspectors. And all because many drivers allow themselves to drink too much and arrogantly drive. It is a big mistake to assume that an hour and a half is enough to take a nap to weather the alcohol from the body. 100 grams of cognac from a human body weighing 70 kg is completely excreted after 4-5 hours, and before that time, the blood contains approximately 0.55 ppm of pure alcohol.

What does ppm say

The content, or concentration of alcohol in the bloodstream in the international system is designated as BAC (Blood Alcohol Concentration) and is measured in ppm. Ppm (‰) indicates the concentration of ethanol in milliliters per 1 liter of blood. In other words, this is the ratio of the volume of alcohol and blood in the body. For example, the result "0.4 ppm" indicates that 1 liter of blood contains 0.4 ml of pure alcohol.

But bare numbers mean nothing to most people. Drivers are the exception. They certainly know for sure that 0.4 ppm in the blood is already a problem with the police. According to the rules of 2016, the driver's blood cannot exceed 0.35 ‰ of ethanol, and the concentration of alcohol in the exhaled air must not exceed 0.16 ‰. By the way, the ppm rate is affected not only by alcohol, but also by some products. For example, non-alcoholic beer, kefir, kvass, curdled milk, yogurt, rye bread sandwiches, overripe bananas and even cigarettes, although they will not affect the level of sobriety, they can noticeably affect blood alcohol levels (especially against the background of a small portion of alcohol already taken).

Why know the degree of intoxication

A few years ago, the ability to take a breathalyzer online for drivers seemed like a pipe dream. Today, a virtual blood alcohol meter can show a fairly accurate result. And knowing the degree of alcohol intoxication, it is easy to calculate the time required for the complete withdrawal of alcohol from the body. Undoubtedly, this information is primarily important for drivers. But in the modern world, when alcohol is one of the most consumed products, many would like to determine how much alcohol the body can take without compromising health and when the drunk alcohol will completely disappear. And this will help the breathalyzer - a unique analyzer of the level of intoxication.

What is the Widmark formula

Most online breathalyzers are based on a formula developed by Swedish researcher Eric Widmark. By the way, it is this formula that forensicists use today and it is from it that the police and paramedics calculate the level of intoxication of the driver.

To determine the concentration of alcohol in the blood according to the formula of a Swedish scientist, it is necessary to divide the mass of the drink drunk (in grams) by body weight (in kilograms) multiplied by 0.6 for girls and women and 0.7 for the stronger sex. The result obtained indicates the dose of alcohol in the blood (in ppm).

How drunkenness affects the body

From 0.2 to 0.29‰

A person still behaves adequately, but measurement with the help of special laboratory devices will already show changes in the blood formula.

From 0.3 to 0.59‰

The person becomes more joyful, relaxed, talkative and less restrained. The first violations of concentration are noticeable.

From 0.6 to 0.9‰

Sensations are dulled, the eyes react poorly to light, peripheral vision deteriorates, and the adequacy of perception of what is happening around is disturbed.

From 1 to 1.9‰

The person becomes more emotional, unrestrained, easily falls into anger. At the level of physiology, reflexes, motor skills (a staggering gait appears), the ability to clearly express thoughts, libido and erection worsen.

From 2 to 2.9‰

In this state, it is easy to fall into a stupor, sensations are sharply reduced, and the risk of loss of consciousness and memory increases.

From 3 to 3.9‰

Loss of control over urination, there is a strong tachycardia, an almost complete loss of control over the body.

From 4 to 5‰ and above

Severe alcohol poisoning. Signs, as with the degree of intoxication of 3.9‰, but more pronounced. The danger of death is very high.

How to use the calculator

Alcohol Calculator is a service with which you can calculate the amount of alcohol in the bloodstream, taking into account portions and the strength of the alcohol you drink. In other words, this is a program for online determination of the degree of intoxication.

But we note right away that a professional blood alcohol calculator is not designed to determine how much alcohol a driver can afford to drink before driving. Even the smallest amount of alcohol is already a reason to use the services of taxi drivers or familiar drivers. A virtual breathalyzer will help to make an approximate calculation of how long after a feast it is safe for the driver to drive again.

The calculator calculates the percentage of BAC, taking into account individual factors:

• body weight;
• fullness of the stomach;
• the amount of alcohol consumed;
• the strength of the consumed drinks.

In addition, the virtual breathalyzer also takes into account what alcoholic drinks and how much were drunk during the feast.

After filling out the form in a split second, the program will calculate the degree of probable intoxication. The breathalyzer will tell you how much per mille of alcohol is contained in the blood and in the exhaled air, and also calculate the approximate time required for the removal of alcohol from the body.

This calculator can also be useful when planning a large feast. With the help of a simple program, it is easy to calculate how much alcohol "for good humor" on average will be needed for one guest. And with this information, it is easy to create a menu and calculate the amount of drinking for the celebration.

Statistics show that almost a third of road accidents are the fault of drunk drivers. Remember that a drunk driver is a danger not only to himself, but also to passengers and pedestrians. Use the calculator to determine how many hours after the feast you can sit down at the "steering wheel". And let nothing overshadow your holidays: neither a headache, nor fines, nor an accident.

Your attention is brought to an alcohol calculator for a driver online - this is a virtual breathalyzer, which has an accurate calculation of ppm in the body (blood) of a drunk person and the time it takes to remove alcohol from the blood, depending on gender, weight and height, time after drinking, degree of alcoholic beverage and quantity drunk on a full or empty stomach.

0.3‰ is approximately 1 bottle of light beer 4.5% vol. (500 ml), but this does not mean at all that the driver can drink beer before driving, because. — it is important- the allowable 0.3 ppm is calculated for the content of any, even a completely non-drinking person, endogenous (internal) alcohol, which is produced in the small intestine, for example, due to fermentation of food.

Therefore, if you drink beer (0.3‰) + your own, internal alcohol (0.3‰) = 0.6‰, which indicates a mild degree of intoxication. And this already threatens with a fine, deprivation of rights, putting the car in a fine parking lot, and in the event of an accident, you are to blame in any way ... (even without guilt, because you have wine in you)

On this page of breathalyzer and determination of ppm in the blood, you will be presented with not one professional alcohol calculator used by forensic experts, but three: Breathalyzer online for recalculating alcohol from one type to another and determining the neurons (nerve cells) killed by alcohol in the cerebral cortex, and also - another calculator for the elimination of alcohol and ppm, the degree of intoxication and after how many hours you can drive.

Table for removing alcohol from the body (blood) - Widmark's formula ^

It can help you in calculating the degree of intoxication and the withdrawal of alcohol from the body table of alcohol excretion from the body:

An accurate calculation of the output of alcohol (ethanol and its decay product - acetaldehyde, then turning it into harmless acetic acid) is possible only in laboratory conditions. However, the alcohol elimination table based on the formula of the Swedish chemist Eric Widmark, which is used in forensic medicine, can help you determine the degree of intoxication from the amount of alcohol consumed, its strength and body weight.

Widmark formulas:
(1), where

• c - blood alcohol concentration in ‰,
• A - the mass of the drink drunk (in terms of pure ethanol) in grams,
• m - body weight in kilograms,
• r is the Widmark distribution coefficient (0.70 for men, 0.60 for women).

To obtain the real concentration of ethanol in the blood from the calculated by formula (1), it is necessary to subtract from the mass of drunk alcohol A from 10% to 30% of the so-called. deficiency of resorption, since part of the alcohol does not reach the peripheral blood.

The following formula is used to calculate the amount of alcohol consumed: (2)

Examination of the state of alcoholic intoxication of the driver ^

If the traffic police inspector observes one or more of the six signs listed below in the driver, then this gives sufficient reason to believe that the driver is in a state of alcoholic or other intoxication - and the driver can be examined for the presence of ppm ethyl alcohol in the blood (in the exhaled air) place, by exhaling into a breathalyzer or referral to a medical facility)

1. alcoholic (or fume) breath odor
2. poor coordination and unsteady posture
3. tremor of fingers
4. incoherent speech
5. sudden change in skin color on the face
6. inappropriate behavior

Alcohol calculator ppm online ^

This online alcohol calculator will help the driver determine when he can drive his car after drinking alcohol.

To pass this test and the calculator calculated the ppm and time of ethanal removal from the body, you need to indicate in the program your gender (M or F), how much alcohol-containing drinks you drank and what degree of strength they had, and also how many hours have passed since the last intake of alcoholic beverages.

So, get tested on an alcohol calculator for drivers online:

Breathalyzer online - accurate conversion to another type of alcohol ^

If you need to recalculate one alcoholic beverage by strength into another, weaker or stronger (for example, 100 grams of forty-proof vodka into beer 4.5% by volume, or vice versa), then this online breathalyzer will do it in a second.

Also, this online breathalyzer (liquor conversion calculator) will show you in the results how many neurons (nerve cells) you killed by drinking this or that dose of alcohol.

Professional alcohol calculator for driver online ^

The online alcohol calculator presented below for the driver is a professional and fairly accurate tool for determining the level of ethanol in the blood and the rate of its excretion from the body in ppm.

To determine your degree of intoxication and the time for removing alcohol from the blood, you need to indicate your gender, weight and height, the number and strength of alcoholic beverages (if there were several of them with different strengths, indicate all), and the fullness of the stomach - was it full or empty during time of drinking.

The graphs for the rate of alcohol removal in ppm can be left standard, without change (if you don’t know exactly at what rate ethanol “weathers out” individually for you).

ATTENTION! These alcohol calculators do not guarantee 100% accuracy in the withdrawal of alcohol from the blood (body), because. there are other individual characteristics of an individual that affect the absorption and excretion of ethanol and its decay products from the body.
