About the BAC Calculator
The BAC Calculator estimates your blood alcohol content based on the drinks you consumed, your body weight, and the time elapsed since your first drink. The result is an estimated BAC percentage you can use for safety awareness.
It applies the Widmark formula, the standard method for estimating blood alcohol content. The calculation uses the alcohol volume in your drinks, your weight, your sex for the distribution factor, and elapsed time for metabolic elimination. Enter drink details as accurately as you can, including size and alcohol percentage. Individual results vary, so treat the estimate as an approximation and consider a professional for decisions with legal or safety consequences.
