Alcohol BAC calculator

Estimates blood alcohol concentration with the Widmark formula from drinks, strength, weight and hours, with a time-to-zero estimate.

Enter your details and drinks for an estimate.

This is the Widmark formula over what you typed, which makes it a population-average estimate, never a test. It cannot see what you ate, your tolerance, medication, or how generously the drinks were poured. It is not a guide for driving: legal limits vary by country and there is no level of alcohol that makes operating a vehicle safe. Nothing you type is sent anywhere or stored.
