Check Your Blood Alcohol Content

Check Your Blood Alcohol Content (“BAC”)

There is no blood alcohol calculator that is 100% accurate because of the number of factors that come into play regarding the consumption and reduction (burnoff) rates of different people. Factors include the sex (male/female) of the drinker, differing metabolism rates, genetic make-up, various health issues and the combination of medications that might be taken, drinking frequency, amount of food in the stomach and small intestine and when it was eaten, elapsed time, and others. The best that can be done is a rough estimation of the BAC level based on known inputs.

BAC is the concentration of alcohol in blood. It is usually measured as mass per volume. For example, a BAC of 0.02% means 0.2% (permille) or 0.02 grams of alcohol per 100 grams of individual’s blood, or 0.2 grams of alcohol per 1000 grams of blood.

If you would like to get a rough estimate of what your BAC would be at the end of the night, use the BAC Calculator below to help you make better decisions.
