快速计算您的血液酒精含量
Written by The Kalcule Team
使用我们的计算器估算你的血液中的酒精含量（血液酒精浓度）。跟踪你的酒精消耗量，并了解不同饮料如何影响你的血液酒精浓度。
为什么血液中的酒精含量很重要
了解你的血液中的酒精含量对于做出关于饮酒和驾驶的明智决定至关重要。血液中的酒精浓度会影响你的判断力、协调能力和反应时间，因此监控你的酒精摄入量是非常必要的。
如何使用血液酒精浓度计算器
- 1请输入您的性别和体重
- 2输入所消费饮料的数量和种类
- 3请指明自您喝第一杯酒起已过去的时间。
- 4获取您的预估血液酒精浓度和清醒所需时间
安全饮酒小贴士
饮酒前和饮酒时要吃东西，喝酒间隔时要用水来调节自己的节奏，并且始终规划安全的交通方式。记住，血液酒精浓度计算器只是估算值，不应用来判断你是否适合开车。
常见问题解答
在这里找到关于血液中的酒精含量（血液酒精浓度），酒精代谢，以及体重、性别和时间等各种因素如何影响您的血液酒精浓度的常见问题的答案。了解安全饮酒的做法以及血液酒精浓度计算的局限性。
酒精浓度计算器提供基于一般因素的估算值。个人的新陈代谢、食物摄入、药物使用以及其他变量都可能影响实际的血液酒精浓度。切勿仅依靠计算器来判断您是否适合驾驶。
平均而言，身体每小时大约以{rate}%的速度代谢掉酒精。然而，这个速度因人而异，也受环境影响。确保自己完全清醒的唯一方法是让足够的时间过去，期间不饮酒。
No. Never. The Widmark estimate ignores gastric emptying, recent food, medication, illness, drinking pattern and individual metabolism. If you have been drinking, do not drive. Use a designated driver, taxi or public transport.
Erik Widmark’s equation estimates blood alcohol from alcohol dose, body weight and a sex-specific volume-of-distribution factor, minus an elimination rate over time. It is a forensic approximation, not a breathalyser.
Body size, sex-specific water fraction, time since drinks and number of drinks all change the result. Even then, real blood concentrations scatter around the estimate.
A commonly used average is about 0.015% BAC per hour, with a wide individual range. Coffee, cold showers and “sober up” myths do not speed liver metabolism.
Food, especially with fat and protein, slows absorption so the peak is later and often lower. It does not cancel the alcohol already absorbed.
No. Limits differ by country and by driver category (for example learners). This site does not give legal advice. Check the law where you are.
Many medicines interact with alcohol or increase impairment even at a low BAC. That interaction will not show up in this formula. Ask a pharmacist or clinician.
A properly calibrated device measures what is in your breath now. This calculator guesses from inputs you type. Neither is a licence to drive after drinking.

保持安全与负责
将这个计算器作为一个教育工具来了解不同因素如何影响你的血液酒精浓度。总是谨慎行事，切勿酒后驾车。如果你计划喝酒，提前安排安全的交通工具。
What Widmark can and cannot do
The Widmark equation estimates concentration from dose, body mass and a distribution factor, then subtracts elimination over time. Real measurements scatter around that line because absorption, food, sex-specific water fraction and liver rate all vary.
This page will never tell you that you are fit to drive. Impairment starts below many legal limits, and the estimate can be wrong in either direction. If you drank, do not drive.
Time is the only sobering agent
Caffeine, exercise and cold water change how awake you feel, not how fast the liver clears ethanol. Plan transport before the first drink. Related articles on this site cover effects, “sober up” myths and addiction resources — none of them replace professional help.
