About this tool

Enter the number of standard drinks (14 g of alcohol each), your weight, sex and the hours since you started. The tool uses the Widmark formula to estimate BAC and the hours needed to reach zero. It is an estimate only and must never be used to decide whether it is safe to drive.

How the estimate works

The Widmark formula divides the alcohol consumed by body weight and a distribution factor, about 0.68 for men and 0.55 for women, then subtracts about 0.015 percent per hour for elimination.

Why it is only a guide

Real BAC depends on food, medication, health, drink strength and how quickly you drink. Two people of the same weight can differ widely. Legal limits vary: 0.08 percent in most of the US and England, 0.05 percent in many European countries and Australia.

Safety

The only safe amount before driving is none. Use a taxi or a designated driver.

計算示例

With the boxes at their starting values (Standard drinks (14 g each): 3; Body weight (kg): 75; Sex: Male; Hours since the first drink: 2), the tool shows: As a percent: 0.052%; Hours to reach zero: 3.5; Estimated BAC (%): 0.052. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.
