Sobering up time table. Alcohol intoxication calculator for drivers

Introduction maximum quantity blood alcohol levels when driving vehicle- one of the main means of state regulation of road safety.

As a unit of measurement alcohol intoxication appears per mille- the ratio of grams of alcohol per liter of blood.

The maximum ppm threshold when driving differs in different countries Oh. For example, in Canada the permissible ppm is 0.8, which allows you to drink a glass of beer before the trip.

What is permissible norm drinking alcohol while driving in Russia? And what will happen if it is violated? Let's figure it out.

Permissible alcohol limit while driving in ppm

For three years, from 2010 to 2013, the permissible rate was “zero” ppm, which completely excluded the possibility of a dispute with traffic police inspectors. However, this norm had many drawbacks. Consumption of many foods shifts the blood alcohol content above zero - chocolate and bakery products, kefir and kvass, juices, yoghurts and overly ripe bananas. Not to mention non-alcoholic beer or many medications.

In 2013, the effect of “zero” ppm was canceled. Now driving a car is allowed if the breathalyzer shows when exhaling no more than 0.16 mg per liter of air. This is the new measurable threshold for intoxication. But ppm is a value that calculates the alcohol content in the blood, not in the air.

0.1 ppm, contrary to popular belief, is not equal to 1 mg/l. To calculate it, a formula is used in which 0.1 ppm contains exactly 0.045 mg/l of alcohol. After calculations, we find that the permissible maximum ppm for the current year is approximately 0.35.

The new standard has minimized the measurement error of the breathalyzer. How to determine the approximate ppm content in the blood after consumption alcoholic drinks?

Determination of blood alcohol content

the number of degrees in alcohol consumed and the dose drunk;
weight and gender of a person;
state internal organs and genetic predisposition;
availability of snacks, their quality and quantity;
general condition of a person.

It is not difficult to exceed the legal limit for alcohol while driving. 1 ppm is already serious intoxication, which is achieved after drinking an entire 0.5 liter bottle of vodka by a strong man weighing 70-75 kg. The maximum permissible rate is 5 or 6 units per mille. It's already lethal dose.

In theory, 100 grams of vodka gives 0.55 ppm, and a 0.5 liter bottle of beer – 0.32. In practice, when tested on a breathalyzer, the result may be completely different. The device can overestimate ppm (for example, with alcohol vapor in the lungs after sobering up) or reduce it. To avoid this ambiguity in the definition of intoxication, the critical value of ppm was increased to 0.35.

It is difficult to calculate the ppm content in the body on your own. There are ready-made tables for this, in which a glass of vodka with a capacity of 100 grams is taken as one dose. The results are also quite arbitrary, but can sometimes be useful.

We offer 2 tables with ready-made calculations - separately for men and for women.

How long does it take for alcohol to be detected when exhaled?

To determine the time during which it is better not to get caught by traffic police inspectors after drinking alcohol, it is necessary to take into account many factors, including the rate of absorption of alcohol, the time it takes to be removed from the body and body weight. The highest blood alcohol content is achieved 30 minutes to 2 hours after consumption, depending on the type of drink and the presence of a quality snack.

Many drivers are interested in knowing how long it takes for alcohol to completely disappear from the body. General rule Here it is - you are strictly forbidden to drink alcohol before a planned trip. If you still have a whole day left before driving the car, you can drink freely. The rules are not ironclad, but quite effective.

We suggest looking at a table that shows how long it takes for various alcoholic drinks to be eliminated from the human body. It should only be taken into account that these data are seriously influenced by a person’s weight, gender and health status.

TIME FOR REMOVING ALCOHOL FROM THE BODY (PPMILLE OF ALCOHOL WHEN EXHALATED AIR)

Type of drink, alcohol content in%	Quantity (ml)	Time during which alcohol vapor can be detected in exhaled air (hour)
Vodka (40)	50	1,0-1,5
Vodka (40)	100	3,0-3,5
Vodka (40)	200	6,5-7,0
Vodka (40)	250	8,0-9,0
Vodka (40)	500	15,0-18,0
Cognac (40-45)	100	3,5-4,0
Champagne	100	1,0
A mixture of cognac and champagne	100-150	4,0-4,5
Port wine	200	3,0-3,5
Port wine	300	3,5-4,0
Port wine	400	4,5-5,0
Beer (2.8)	500	Not defined
Beer (3.4)	500	Not defined
Beer (6)	500	20-45 minutes

In general, for healthy man weighing 80 kg, the weathering time of alcohol will be as follows:

a bottle of beer 0.5 – 2 hours (3 hours when drinking strong beer);
200 g of wine – from 2 hours;
100 g of vodka - you will have to wait 3.5 hours, 300 g - 11 hours;
A whole bottle of strong alcohol (40-45 degrees) – 17 hours.

Alcohol elimination time for people of different weights is easily calculated using proportions. But do not forget that the error of instruments for checking the state of intoxication is from 0.1 to 0.16 ppm. To be on the safe side, it is better to add at least an hour to the given data.

Punishment for exceeding the permissible ppm in the body

In 2019, the penalty for driving in drunk quite severe:

for the first driving while intoxicated - a fine of up to 30 thousand rubles and a sentence of one and a half to two years;
repeated violation of the law - the fine increases to 50 thousand plus deprivation of rights for 3 years;
if there is a fine for drunk driving, driving a car will entail administrative arrest for a period of 10 to 15 days;
if the car owner does not want to be examined for the fact of intoxication, the punishment against him will not be removed (it is the same as for the first violation).

IN State Duma There is constant talk about toughening penalties for drunk driving. It is possible that the amount of fines will increase significantly in the future. By the way, transferring the right to drive a vehicle to a drunk person is punishable in the same way as driving independently while drunk.

Tips for avoiding problems with road inspectors

In addition to the fact that drinking alcohol and driving a car should be kept as far apart as possible, you should also adhere to less obvious rules:

You should not use medications before traveling, especially those containing ethyl alcohol;
The consumption of kvass, fermented milk products and juices, although very rare, can still increase the amount of alcohol in the body. Especially if we're talking about about natural homemade products, not store-bought ones;
It will most likely not be possible to fool a breathalyzer; this can only lead to an invitation to take an alcohol test at a specialized medical institution;
Don't try to hide alcohol with mouthwash or chewing gum;
In any case, you should not conflict with the traffic police inspector and say rude things to him.

How to increase the speed of alcohol removal from the body? Good decision There will be a contrast shower, sound and long sleep, hot baths. Proper, healthy food and long walks in fresh, fresh water work well to eliminate alcohol. clean air. Let us remind you that when exhaling air, the permissible ppm is no more than 0.35.

IN Lately The problem of drunk drivers is being actively discussed. The state is introducing new penalties for driving while intoxicated. How to determine when you can drive? To answer this question it will help alcohol calculator (alcocalculator). He will calculate the time after which the alcohol in the blood will disappear and you can safely get behind the wheel. For the calculation, the world-famous formulas of Eric Mateo Prohet Widmark and Seidl, which are used by criminologists, are used. We can safely say that this is the most accurate alcohol calculator.

Online blood alcohol calculator

According to the results of statistical studies, 30% of road accidents occur due to the fault of drunk drivers. To avoid being one of them, to control your condition it is enough to use this alcohol intoxication calculator. It will quickly show online how many ppm is in blood and when you can get behind the wheel. Especially now, when the blood alcohol level must be zero and it is very easy to lose your license. So our calculator can be used as alcohol calculator for drivers.

(or alcocalculator) can be useful to determine alcohol aging time. By entering your weight and height, as well as the amount of alcohol consumed and its strength and indicating whether the drinks were drunk on a full or empty stomach, you can find out how long it will take there will be no traces of alcohol in the blood. It is possible to specify up to 5 different drinks. Exact formulas allow you to determine How long does it take for alcohol to dissipate?. Moreover, the calculator will show ppm in the blood after drinking, as well as time it takes for alcohol to leave the blood(minimum - for people who are able to quickly process alcohol, average - for most people and maximum for people who have low alcohol withdrawal rate).

The permissible blood alcohol level varies from country to country. .

Blood alcohol level

Blood alcohol level depends on the state the person was in when drinking alcohol - depends on the degree of filling of the stomach.

Alcohol calculator for a wedding

And this question will help answer alcohol calculator. It is enough to know to what state the guests want to get drunk and how many guests will celebrate. By calculating the required amount of alcohol in the blood for one guest, we can easily find out how much alcohol do you need for a wedding. At the same time, do not overdo it - for fun, the amount of alcohol in the blood should not be raised above 3 ppm. Well, car enthusiasts can easily identify blood alcohol level.

How many ppm are allowed in 2019

In 2019, the permissible level of alcohol in the blood is 0.35 ppm, and in exhaled air 0.16 ppm.

Addendum 2013

How many ppm are allowed?

In accordance with the Federal Law of July 23, 2013 N 196-FZ “On Amendments to the Code of the Russian Federation on administrative offenses and article 28 Federal Law"About safety traffic» from September 1, 2013, the level of alcohol in the driver’s blood is allowed

0.16 ppm in exhaled air

0.35 ppm in blood

Our calculator also takes this change into account; now you will find out not only the time for complete elimination of alcohol from the body, but also the time for elimination before acceptable values. Thus our online calculator now it's easy to answer the question how many ppm is allowed in 2013. In this regard, we are the first to offer a calculator that takes into account the new standards of 2013. Your rating

Alcohol in the blood: reasonable boundaries, and what lies beyond them

U different people at at different levels alcohol in the blood, external manifestations may vary. This is taken into account when conducting forensic analysis, especially abroad. There is a whole complex computer programs and calculations to determine the individual permissible amount of alcohol in the blood.

Above are tables about the alcohol content in a person’s blood, the degree of influence of alcohol in the blood on behavior and emotional condition person, as well as how long alcohol stays in the blood after drinking it, depending on the amount of this “potion” taken.

Alcohol in the blood is not appropriate in a good way, unless it is meant, which is permitted by law, and for some people it is always present (alcohol - like a large number of other chemical substances naturally present in the human body). Alcohol in the blood increases its content at banquets and holidays. Drinking alcohol is very ancient tradition, existing in almost all human cultures. By the way, the Bible does not prohibit drinking within reasonable limits, as long as wine drinking does not turn into an uncontrolled passion.

But I appeal to you, readers, know when to stop! The table clearly showed to what extent alcohol in the blood can soar, and from there you can see what this is fraught with.

It is already known that death occurs when alcohol in the blood reaches 4 ppm... this is in theory. Exceptions happen in everything. A case of impossible, simply hellish intoxication was recorded. In 2005, a 67-year-old resident of Bulgaria was hit by a car, and in the hospital his alcohol level was determined to be 9.14 ppm! The man, in theory, should have been dead at least twice, instead he spoke coherently and almost =) thought logically!!

How to urgently reduce blood alcohol

It happens when it is necessary urgently reduce blood alcohol levels. There are many ways to do this. These are special medical supplies, and numerous folk remedies. You can drink a glass of sunflower oil - it’s not very pleasant, but it helps clear your mind, and it will treat you more neutrally;) Also known are going to the bathhouse, strong tea, and coffee. If a drunk person loses consciousness. You can rub his ears, the blood rushing to his head will slightly disperse the alcohol in the blood and slightly dispel the intoxication. Some methods of quick sobriety overload the heart, be careful, for example, going to the bathhouse in drunk or taking an ice cold shower! It is easier to initially control alcohol in the blood and not bring yourself to extreme intoxication.

“You need to have a snack”

By the way catchphrase“I need to have a snack” didn’t come out of nowhere. After all, alcohol consumed with food will be absorbed by the intestines much more slowly than on an empty stomach. So the snack affects your alcohol level.

To control blood alcohol easily and without nerves, purchase or.

Celebrations and feasts are rarely complete without alcoholic beverages. And if you have to go to work tomorrow or today, it’s a good idea to know your blood alcohol level so you can drive your own car without fear. What is ppm, how to determine the exact unit knowing how much was drunk and keeping calm, how and how to measure the amount of residual ethanol - we’ll tell you about this.

What is ppm?

The concept has precise definition is one thousandth, used to indicate the presence of thousandths in one whole. Permille is used to measure the concentration of alcohol residues in the blood and exhaled air of a person. Ethanol concentration is an indicator for motorists and a guide to action: drive or use public transport.

The ‰ sign is used to denote the indicator, so instead of “one ppm” they write 1‰ and calculate it using a simple formula: divide the integer by a thousand. As a percentage, 1‰ is a tenth of a percent, that is, 1% = 0.1‰.

How to calculate ppm yourself?

To convert percentages to ‰, it is enough to divide the whole number in % by 100, because 1‰ is a tenth of a percent! That is, 40% strength = 0.4‰. And, of course, the same thing is done in reverse: 0.3‰ * 100 = 30%. Thus, a wine of 12% will give a ppm amount of 0.12 and so on.

An indicator equal to 0.2 ‰ will indicate the number of grams of alcohol present in a liter of fluid in the entire human body. The natural “endogenous” standard for any individual is considered to be the norm of 0.3 ‰ - this indicator is always there, regardless of the consumption of alcoholic beverages, and it is this that is taken as the basis for the “zero” ‰.

When drinking an alcoholic drink, the highest concentration of alcohol in the blood is reached in about half an hour. This is where you can quickly calculate the content level ‰. In addition to the fact that the indicator will help determine the ability to drive a car, knowing the rate at which alcohol is eliminated from the body will help to clearly understand the period of time required for complete sobering. But this is precisely what is important for drivers, since in the Russian Federation there is no “permissible level” of ethanol concentration, despite the accepted legislative acts. Getting behind the wheel after drinking even a glass of wine means incurring all kinds of penalties from the traffic police. Well, the consequences of driving while drunk are known to all car owners.

Advice! It has been practically revealed that in an hour, approximately 0.15 ‰ is excreted from the body of a man with a healthy liver. Female body removes ethanol residues much more slowly, the figure varies between 0.8-0.11‰.

Independent determination of the degree of intoxication and an example of calculating ppm

A 23-year-old man weighing 77 kg drank 250 ml of vodka with an alcohol content of 40%.
The ratio of water in the body is considered to be 70%, that is, the volume is calculated as 77 kg * 70% = 53.9 kg.
The ethanol content in the amount drunk can be determined using the formula (0.79 g/ml – density of ethyl alcohol): unit of drink* density. In our case, 250 ml * 40% = 100 ml of pure alcohol, which must also be multiplied by the density (0.79) for a total of 79 g. pure alcohol.
And now the calculation of ppm: 79 g. alcohol divided by 53.9 (total volume of fluid in the body), the total amount is 1.46‰.

Thus, in the body of a healthy man, the alcohol content after drinking a glass of vodka is equal to an indicator that significantly exceeds the permissible 0.3 ‰ at which you can drive. Even taking the value of 10% error as an additional factor, the value remains unacceptable. According to the table of degree of intoxication:

0.3 ‰ – natural “zero” alcohol content level;
0.-0.5‰ – insignificant effect of alcohol on behavioral reactions;
0.5-1.5‰ – state of mild intoxication;
1.5-2.5‰ – average degree of intoxication;
2.5-3.0‰ – a very drunk person;
From 3.0‰ – a lethal dose of alcohol.

It can be revealed that the hypothetical man used as an example is in mild degree intoxication. It will return to normal (with an output of 0.15‰ per hour) in approximately 6-9 hours.

Knowing how to convert ppm to grams and calculate a certain level of residual alcohol content in the blood, you can always understand the extent of your condition. Let us remind you that in order to determine how many ‰ in a gram, it is enough to divide 1 gram by 100. That is, 1 gram. pure alcohol will show 0.01‰. The Code of Administrative Offenses of the Russian Federation warns about the norms for the presence of pure ethyl alcohol in the blood. The indicator is 0.16 mg per liter of air exhaled by an individual. If you make a simple calculation in a ratio of 1:2200 (air: ratio to liquid), you get a figure of 0.352 g/l of blood - the popularly accepted figure of “0.3‰”. From here, calculate how much you can drink before getting behind the wheel.

Based on the data on the number of ppm, we can conclude about the presence of alcohol intoxication and the degree of intoxication of the body. By ppm, which is denoted as ‰, we mean a thousandth or a tenth of a percent of alcohol in the blood (1 l). This unit of measurement shows the concentration of ethanol in a liter of blood. That is, an alcohol level of 1.2 ‰ means that a liter of blood contains 1.2 ml of ethanol and 998.8 ml of pure blood.

This value demonstrates the mass ratio, which determines different number ppm readings when drinking alcohol with different densities.

Estimation of blood alcohol content

When an alcohol-containing liquid enters the body, it passes through the esophagus into the stomach and through its walls into the blood. That is why the maximum concentration of alcohol in the blood reaches its peak half an hour after drinking alcohol.

As for information about the amount of ppm in the blood, it allows you to obtain the following:

Have information about the alcohol content in the body at a certain point in time;
Calculate the amount of alcohol you can drink to reach or not exceed a certain ppm level;
Calculate the time necessary for the body to get rid of alcohol.

The last two points are especially relevant for drivers in the Russian Federation, since the law allows you to drive a car without the risk of losing your driver’s license if you have 0.3 ‰ in your blood. As for the permissibility of drinking alcohol by a motorist, everyone decides this question for themselves. Much more relevant for the majority is what a breathalyzer will show when a driver is checked by a traffic police officer. Theoretically, even on the day of the trip, you can allow yourself to drink a little, since ethanol is naturally eliminated by the body. On average per hour male body neutralizes 0.15 ‰, and for women – 0.12 ‰, but in practice, this value can vary both up and down due to the characteristics of the body, health status, gastric secretion, medications taken, etc.

Calculation of blood alcohol content

To calculate, you can use our alcohol calculator:

To calculate the amount of ethanol in the blood, you must have the following initial data:

weight and gender of the individual;
percentage of available fluid to total body weight;
the amount of ethanol in the consumed volume of alcohol-containing liquid.

On average, the percentage of water in male body is 70%, for women this figure is lower – 60%.

Example: a man weighing 80 kg drinks 200 ml of vodka, the alcohol content of which is 40%. To calculate ethanol in the blood, you need to calculate the amount of water in the body, that is, 80 kg * 70% = 56 kg. To determine the mass of ethanol consumed, it is necessary to calculate the amount of alcohol in alcohol: 200ml*40%=80ml. Since the density of ethyl alcohol is 0.79 kg/l, the mass of ethanol will be 63.2 g. Taking into account the 10 percent error in determining the amount of ethanol, we obtain the weight of ethanol equal to 56.88 g.

As a result, the alcohol content in the man’s blood is 63.2/56.88 = 1.11 ‰.

The calculated value takes into account only a few factors, while the actual ethanol content in a person’s blood is affected by a whole list of factors, which is reflected in the breathalyzer reading:

quality of alcohol consumed;
time of last meal;
presence of an allergy or individual reaction to alcohol,
the time period during which a person drinks alcohol.

You can assess a person’s condition using the data from the table:

Permille level, ‰	Degrees of intoxication	Symptoms
Less than 0.3‰	Sober	This level of alcohol in the blood does not exceed the natural level and therefore does not affect the body
0.3-0.5‰	Minor intoxication	Minor effect on the body
0.5-1.5‰	Mild degree of intoxication	State of euphoria good mood, sociability, expressive facial expressions, precision of movement is lost.
1.5-2.0‰	Moderate intoxication	Deterioration in mood, aggressiveness, sadness, touchiness, inadequate reaction, slurred speech, impaired coordination.
2.0-3.0‰	Severe intoxication	Loss of consciousness, possible coma, epileptic seizures.
3.0-5.0‰	Severe degree of intoxication	, coma, possible death
More than 5.0 ‰	Lethal dose	Death

How much to drink and drive?

By law, the driver is generally prohibited from taking any drugs or alcohol. As for the permissible level of alcohol content of 0.3 ppm, it is determined by chemical processes occurring in the body - these can be fermentation reactions in the intestines caused by microflora, consumption of overripe fruits, baked goods, kefir or kvass. Also a small amount of ppm provides endogenous alcohol produced by the body. Don’t forget about consuming medications containing alcohol, etc.

However, you can calculate the number of alcoholic beverages, the consumption of which will allow you to remain within the limits:

Half a liter of light beer with a strength of up to 5% - its consumption will increase the ethanol content in the blood by 0.2-0.4 ‰. It is worth noting that such a dose causes a decrease in attention and reaction, so that the driver loses concentration.
A liter of beer provides 0.5-0.8 ‰. In this state, the driver is not able to quickly navigate, keeping his attention on fast-moving objects in changing lighting conditions.
3 or more bottles of beer will provide 0.8-1.2 ‰ in the blood - this is the ethanol content that is most often found in drunk drivers involved in accidents. This suggests that motorists do not adequately assess their own state when slightly intoxicated. If the alcohol content is above 1.3 ppm, the driver will have an accident in 95 out of 100 cases.

To quickly and accurately determine the amount of ethanol in the blood, breathalyzers are used that evaluate. If you wish, you can buy such a device for private use in order to be sure that the traffic police officer will not have grounds for depriving you of your license for drunk driving.
