About Alcohol Calculator

Calculates the time for your body to metabolize alcohol and estimates when it is safe to drive, based on drink type and amount.

⚠️ Results are general estimates only. Actual metabolism varies by individual. Driving under the influence is illegal.

📖How to Use
  1. 1Enter the type, volume, and alcohol percentage of your drinks
  2. 2Enter your weight and gender to estimate blood alcohol concentration (BAC)
  3. 3See the metabolization forecast based on time since drinking
💡Tips & Knowledge
  • Pure alcohol (g) = volume (ml) × ABV (%) × 0.8 (specific gravity of alcohol)
  • Japan's guideline for moderate drinking is 20 g of pure alcohol per day (≈ 1 medium beer)
  • Individual variation is significant — use this as a guide only. Always check before driving
