A BAC (Blood Alcohol Concentration) calculator estimates the percentage of alcohol in your bloodstream based on factors like your biological sex, weight, height, number of drinks consumed, type of drinks, and time spent drinking. It typically uses the Widmark formula or similar algorithms to provide an estimate. Here are key points about BAC calculators:
- They estimate BAC to help understand intoxication levels but should not be used to determine whether it's safe to drive.
- Factors like body weight, sex, metabolism rate, and alcohol content affect BAC.
- The legal driving BAC limit is usually around 0.05% to 0.08%, depending on the country.
- Most calculators ask for inputs such as biological sex, weight, height, number and strength of drinks, and drinking duration.
- These calculators also estimate how long it will take to metabolize the alcohol and return to 0% BAC.
One example is Drunk Calc, which uses a comprehensive algorithm to give an accurate estimate of your BAC and predicts peak BAC and when it will reach zero.
