Our calculator uses the Widmark Formula, the scientific standard for estimating blood alcohol concentration.
The core equation is: BAC = [Alcohol (g) / (Weight (kg) × r × 10)] - (β × Hours)
BAC is influenced by your body mass, biological sex, the amount of pure ethanol consumed, and the time elapsed since consumption began. Note that food intake, medication, and individual metabolism can significantly alter these results.
Estimate your blood alcohol concentration (BAC) and time to sober using the Widmark formula.
