What is Blood Alcohol Content (BAC)?
BAC refers to the percentage of alcohol present in a person’s bloodstream. For example, a BAC of 0.05% means there is 0.05 grams of alcohol for every 100 ml of blood. It is used medically and legally to assess intoxication.
Our tool uses the standard Widmark Formula to calculate BAC based on gender, weight, amount consumed, and time elapsed.
