How long does alcohol take to break down?
Breakdown time cannot be determined by the number of cups alone. It is determined by the amount of ethanol taken and the individual course of metabolism.
How long does alcohol take to break down?
Compare common servings and amounts of pure ethanol. This module illustrates the conversion at 8 g/h, not the individual sobering time.
Illustrative conversion: grams of ethanol ÷ 8 g/h. It does not include absorption or body parameters and is not identical to the main calculator model. The result is not a predictor of sobriety or a basis for driving.
What does the degradation time depend on?
The amount of ethanol is also determined by individual metabolism and the course of absorption. A larger glass of wine can contain a similar amount of alcohol as a large beer.
Can alcohol stay in the blood for the next day?
Yes, the model can still show a non-zero level the next morning with a larger amount. The actual course cannot be confirmed by calculation.
How to find out the exact time of sobriety?
The amount of drinks alone is not enough to reliably determine the exact time. The Internet model does not replace measurement.
Source of illustrative value: NHS - Alcohol units. The NHS describes around 8g per hour for the average adult, with individual variations.

Most ethanol is metabolized in the liver. Enzymes gradually convert it into acetaldehyde and then acetate. Genetic and environmental differences influence the course.
What AlcoCalc Assumes
The tool calculates a model removal of 0.15 ‰ per hour from one common level. This value does not vary from person to person and is not a measurement of your metabolism.
Example of time to zero
If the model level after absorption was 0.60 ‰, at 0.15 ‰/h it would mathematically drop to zero in 4 hours. It is an illustration of an assumption, not a recommendation of when to drive.
Why the result may not fit
The tool does not know individual absorption, body composition, health status, or medications. Therefore, screen time must not serve as a confirmation of sobriety.
