Blood Alcohol Content (BAC) Calculator
This calculator estimates your Blood Alcohol Content (BAC) or Blood Alcohol Level (BAL) based on your weight, gender, the number of drinks consumed, and the time elapsed. It helps you understand your level of intoxication and potential impairment after alcohol consumption.
BAC and BAL Estimator
Widmark Formula for Blood Alcohol Content
Where:
- $$A$$ = total alcohol consumed in ounces (oz)
- $$W$$ = body weight in pounds (lbs)
- $$r$$ = alcohol distribution ratio (0.73 for men, 0.66 for women)
- $$H$$ = hours since drinking began
- $$0.015$$ = average alcohol metabolization rate per hour
The BAC calculator is a useful tool to estimate how intoxicated a person might be after consuming alcohol. It uses the Widmark formula to determine the percentage of alcohol in the bloodstream. Knowing your BAC can help make informed decisions regarding driving, physical activity, or health risks. Keep in mind that individual variations in metabolism, food intake, and health conditions may influence actual alcohol levels. The results are estimates and should not be used to justify unsafe behavior.
