चरण-दर-चरण मार्गदर्शक
- 1Widmark formula: BAC% = (Alcohol grams) / (Body weight kg × 1000 × r) − 0.015 × hours
- 2r = 0.68 (males), 0.55 (females) — distribution factor
- 31 UK unit = 10ml pure alcohol = ~8g
- 4Alcohol eliminated at ~0.015% per hour (linear, not exponential)
Worked Examples
इनपुट
4 pints (4% lager) · 70kg male · 2 hours drinking
परिणाम
BAC ≈ 0.087% (over UK legal limit of 0.08%)
Drive limit 0.05% in Scotland, 0.08% in England/Wales
