Other tools you may find usefulAlcohol and permille calculator
The alcohol calculator estimates the approximate concentration of alcohol in the blood (in permille) and the approximate time needed to sober up, based on body weight, gender and the amount of alcohol consumed. The result is for illustrative purposes only and cannot be the basis for a decision to drive a vehicle. The tool is free and runs in your browser.
How permilles are calculated
Estimated alcohol concentration is calculated based on the amount of pure alcohol, body weight and depending on gender (Widmark's formula). The body metabolizes alcohol at an approximately constant rate, which allows us to estimate the sobering time.
Why is it just an estimate
The actual concentration depends on many factors: drinking rate, meals, metabolism, medications and health condition. Therefore, the calculator result is indicative and may differ significantly from the actual measurement.
How to use the calculator
- Enter your body weight and gender.
- Enter the type and amount of alcohol consumed.
- Determine the time since consumption.
- Read the approximate permille and approximate sobering time.
Important Disclaimer
The calculator is for informational and educational purposes only. It is not used to assess the ability to drive a vehicle. Never get behind the wheel after drinking alcohol - the only reliable method of measurement is an approved breathalyzer, and the safest level behind the wheel is 0.0‰.
Permissible permille limit in Poland
There are two thresholds in Poland.0.2–0.5 per milleis a state after drinking alcohol - an offense (fine, driving ban).Above 0.5 per milleis a state of intoxication - a crime under the Penal Code. The thresholds also apply to cyclists and electric scooter drivers (for them the penalties are milder, but detention and fines are real). In practice, even one beer can take you over the 0.2‰ threshold - so simply do not get behind the wheel after drinking alcohol.
How long does it take to sober up after drinking beer, wine and vodka?
The liver metabolizes alcohol at a constant rate of approximately0.1-0.15 per mille per hourand this cannot be accelerated by coffee, a cold shower or food. Approximate values for a man approx. 80 kg (women achieve higher concentrations with the same dose):
| Drink | Pure alcohol | Peak concentration (approx.) | Time to sober up |
|---|---|---|---|
| Beer 0.5 l (5%) | ~20 g | 0.3–0.4‰ | 2–4 h |
| Glass of wine 150 ml (12%) | ~14 g | 0.2–0.3‰ | 2–3 h |
| Glass of vodka 50 ml (40%) | ~16 g | 0.2–0.3‰ | 2–3 h |
| 2 beers 0.5 l | ~40 g | 0.6–0.8‰ | 5–8 h |
| 0.5 l of vodka | ~158 g | 2.5–3.5‰ | 20–30 h (!) |
After a party, you may still havein your blood the next day at noon. The calculator will help you estimate when the concentration will drop to zero - but the result is only indicative.
How the calculator calculates per mille - Widmark's formula
Calculations are based on the classic Widmark's formula:‰ = A ÷ (m × r), where A is the mass of pure alcohol consumed in grams, m - body weight, and r - distribution coefficient (approx. 0.7 for men and 0.6 for women, because the water content in our bodies differs). Already metabolized alcohol is subtracted from the result (time × burning rate). The actual concentration also depends on what you ate, how fast you drink, your age and genetics - which is why no calculator can replace a breathalyzer, and a breathalyzer cannot replace common sense.

FAQ
Is the result accurate?
No. This is an estimate based on Widmark's formula. The actual concentration depends on many individual factors and can vary significantly.
Can I drive a car on this basis?
No. The calculator does not replace a breathalyzer and cannot be the basis for decisions about driving. Do not drive after drinking alcohol.
How quickly does the body sober up?
The pace is approximately constant but individual. It can't be speeded up safely with coffee, showers, or food.
Is the tool free?
Yes, the alcohol calculator is free and informative.
