Widmark Blood Alcohol Formula
Transparent mathematical methodology explained in plain English.
BAC % = [ (Grams Alcohol Consumed / (Weight in Grams × r)) × 100 ] - (Beta × Hours Elapsed)Clinical equation where r is gender body water factor (0.68 for males, 0.55 for females) and Beta is the average metabolic clearance rate of ~0.015% BAC per hour.
Variables Explained:
- Standard Drinks Consumed: 1 standard drink = 14 grams pure alcohol (12 oz beer at 5%, 5 oz wine at 12%, 1.5 oz liquor at 40%).
- Body Weight (kg / lbs): Total body mass.
- Hours Elapsed: Time elapsed since first drink.
Male (80 kg / 176 lbs) Consuming 3 Standard Beers over 2 Hours
Calculating peak BAC and estimated time to 0.00% BAC.
- Gross BAC: (42 g / (80,000 g × 0.68)) × 100 = 0.0772%.
- Metabolized in 2 Hours (0.015%/hr): 2 × 0.015% = 0.0300%.
- Current BAC: 0.0772% - 0.0300% = 0.047%.
- Hours to 0.00% Zero BAC: 0.047% / 0.015%/hr = ~3.1 additional hours.

What is the legal driving BAC limit in the United States and UK?
In the US and UK, the legal BAC driving limit is 0.08% (except Utah at 0.05% and Scotland at 0.05%). Commercial drivers have a stricter 0.04% limit.
Can coffee, cold showers, or exercise speed up alcohol metabolism?
No, the liver metabolizes alcohol at a fixed constant rate of approximately 0.015% BAC per hour; only time can lower blood alcohol content.
