Estimate your blood alcohol content based on drinks consumed, body weight, and time elapsed
1 drink = 12oz beer, 5oz wine, or 1.5oz spirits
Your liver can only process about one standard drink per hour. Drinking faster overwhelms your system.
Women generally have lower water content in their bodies, causing alcohol to be more concentrated.
Eating before drinking can slow alcohol absorption by up to 50%, keeping BAC levels lower.
Blood alcohol typically peaks 30-90 minutes after your last drink, even if you stop drinking.
Alcohol causes your heart to beat faster, which is why you may feel flushed and warm.
While alcohol may help you fall asleep, it significantly reduces sleep quality and REM cycles.
Heavier individuals have more body water to dilute alcohol, resulting in lower BAC levels.
The average person metabolizes alcohol at 0.015% BAC per hour - nothing can speed this up.
This calculator uses the Widmark formula to estimate BAC based on the number of standard drinks consumed, your body weight, gender, and time elapsed. The formula accounts for different body water ratios between males and females, and assumes an average alcohol metabolism rate of 0.015% per hour.
