Blood Alcohol Calculator
Estimate your blood alcohol concentration (BAC) using the Widmark formula.
Widmark BAC Estimation
The Widmark formula estimates BAC based on alcohol consumed, body weight, gender (affecting water content ratio), and time elapsed. One standard drink = 14g of alcohol (12 oz beer, 5 oz wine, 1.5 oz spirits). The body metabolizes about 0.015% BAC per hour. This is an estimate only; actual BAC varies with many factors.
