What is Blood Alcohol Content (BAC)?
Blood Alcohol Content (BAC) is a measure of the amount of alcohol in your bloodstream. It is expressed as a percentage. For example, a BAC of 0.08% means you have 0.08 grams of alcohol per 100 milliliters of blood.
BAC is used to determine legal intoxication for driving and other activities. In the United States, the legal limit for driving is 0.08% in all states.
How BAC is Calculated
This calculator uses the Widmark Formula, which estimates BAC based on:
- Amount of alcohol consumed
- Body weight
- Gender (men and women metabolize alcohol differently)
- Time elapsed since drinking began
The formula is: BAC = (Alcohol consumed in grams / (Body weight in grams × r)) × 100 – (Metabolism rate × hours)
Where r is the distribution ratio (0.68 for women, 0.55 for men) and metabolism rate is typically 0.015% per hour.

Why We Created This BAC Calculator
Alcohol affects everyone differently, and it can be challenging to gauge your level of impairment after drinking. Many people underestimate their BAC levels, which can lead to dangerous situations, especially when driving.

- Educate users about how alcohol affects the body
- Promote awareness of legal drinking and driving limits
- Encourage responsible alcohol consumption
