BLOOD ALCOHOL CONTENT CALCULATOR


This calc will estimate B.A.C.

Use this calculator to get an idea of your alcohol tolerance by weight. Use this calculator at your own risk, it's not meant to be an excuse to get sloppy drunk. Females have a lower tolerance for alcohol so assume the estimated BAC is too low. Based on the quantity of beverages consumed, the alcohol percentage in each drink, the person's weight, and the time spent consuming the drink.
