血液酒精浓度(BAC)计算器
本计算器采用经典的 Widmark 公式，根据你的体重、性别、标准杯数以及自第一杯起经过的时间估算血液酒精浓度(BAC)，并计入身体已代谢的酒精(每小时约0.015%)。它还会估算多久后你才会清醒。实际BAC会因饮食、补水、服用药物和个人代谢而不同，因此请仅将结果作为粗略参考，饮酒后切勿驾车。
仅为基于威德马克(Widmark)公式的粗略估算。许多因素都会改变实际BAC。饮酒后切勿驾车 — 本工具不构成法律或医疗建议。
常见问题
- 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.
