About Blood Alcohol Content
BAC is affected by weight, gender, food intake, and drink strength. Women typically reach higher BAC than men of the same weight due to differences in body water content. The legal driving limit in the US is 0.08% BAC. BAC decreases at about 0.015% per hour. This calculator is an estimate only.
