血液酒精浓度(BAC)计算器

使用 Widmark 公式估算血液酒精浓度 — 基于体重、性别、饮酒量和经过时间

Disclaimer: This calculator provides estimates only. BAC varies by individual metabolism, food intake, and other factors. Never drink and drive.

1 drink = 12 oz beer (5%), 5 oz wine (12%), or 1.5 oz spirits (40%)

Estimated Blood Alcohol Content
4.041%
StatusSevere intoxication
Estimated Time to Sober (0.00%)269.4 hours

Widmark Formula

BAC = (A × 5.14 / W × r) - 0.015 × H

  • • A = alcohol consumed (oz)
  • • W = body weight (lbs)
  • • r = gender constant (0.73 male, 0.66 female)
  • • H = hours elapsed
  • • BAC decreases ~0.015% per hour
