Blood Alcohol Concentration Calculator

Drunk driving kills thousands of drivers and passengers each year in the United States. In fact, the National Highway Traffic Safety Administration reports that 32% of all traffic deaths are caused by drunk driving. Many drivers who have consumed alcohol use a blood alcohol concentration (BAC) calculator to determine if they are legally intoxicated before they drive and injure someone or cause an accident.

A driver's blood alcohol concentration is measured as mass per volume. The calculator uses a variety of factors such as the driver's sex, number of drinks consumed, the number of hours the driver has been drinking, and their body weight to determine if they are over the legal limit, which is currently .08 and above in all states. Although blood alcohol calculators may provide a guide for drivers, they are not always accurate, and it is always better to avoid drinking and driving.
