Alcohol Metabolism Calculator
Calculate blood alcohol concentration and time needed for complete detoxification based on alcohol consumption and personal information
Important Safety Information
- • This calculator is for reference only and individual differences may be significant
- • Never drive after drinking alcohol
- • Driving is prohibited with BAC 0.03% or higher
- • Allow sufficient time for safety before driving
- • Consider individual differences and allow extra time
Generally, a healthy adult's liver breaks down about 7-10g of alcohol per hour. This corresponds to approximately 0.01% to 0.015% in terms of blood alcohol concentration (BAC). This calculator uses the average value of 0.015% per hour.
Widmark Formula: Developed by Swedish physiologist Erik Widmark, this formula estimates blood alcohol concentration considering the amount of alcohol consumed, body weight, and gender. Body water percentage (approximately 0.68 for men, 0.55 for women) is an important variable.
Individual Difference Factors
- Age, health condition, genetic factors
- Food intake status and type
- Fatigue and stress levels
- Medication use
This calculation result is an estimate assuming average conditions, so there may be differences from actual detoxification time. After drinking, be sure to get sufficient rest and never drive.
