血液酒精濃度(BAC)計算機
本計算機採用經典的 Widmark 公式，根據你的體重、性別、標準杯數以及自第一杯起經過的時間估算血液酒精濃度(BAC)，並計入身體已代謝的酒精(每小時約0.015%)。它還會估算多久後你才會清醒。實際BAC會因飲食、補水、服用藥物和個人代謝而不同，因此請僅將結果作為粗略參考，飲酒後切勿駕車。
僅為基於威德馬克(Widmark)公式的粗略估算。許多因素都會改變實際BAC。飲酒後切勿駕車 — 本工具不構成法律或醫療建議。
常見問題
- What is blood alcohol content (BAC)?
- BAC is the percentage of alcohol in your bloodstream, expressed as grams of alcohol per 100 mL of blood. It rises with each drink and falls as your liver metabolizes alcohol over time, and it is the standard measure used in legal driving limits.
- How does the BAC calculator estimate my level?
- It uses the Widmark formula, factoring in your weight, sex, number of standard drinks, and time elapsed. Alcohol is removed at roughly 0.015% BAC per hour, so the tool also estimates when you would return to zero. Results are estimates only.
- Is the calculated BAC accurate enough to drive?
- No. Estimates can differ significantly from a breathalyzer due to food, hydration, medications, and individual metabolism. In many places the legal driving limit is 0.08%, but impairment starts well below that. Never use a calculator to decide whether you are safe to drive.
