计算示例
A 180 lb male who had 3 drinks over 2 hours.
- 01Alcohol = 3 x 14 = 42 grams
- 02Weight = 180 x 453.6 = 81,648 grams
- 03BAC = (42 / (81,648 x 0.73)) x 100 - 0.015 x 2
- 04= 0.0705 x 100 - 0.030 = 0.041%
常见问题
How long does it take to sober up?
Your body eliminates alcohol at roughly 0.015% BAC per hour. There is no way to speed this up. Coffee, food, and cold showers do not lower BAC.
What is the legal limit?
In most US states, the legal BAC limit is 0.08% for adults. Some states have lower limits. For commercial drivers it is 0.04%. For under-21 it is typically 0.02% or zero.
How accurate is this calculator?
The Widmark formula provides an estimate. Actual BAC varies with food intake, drinking speed, medications, liver function, and individual metabolism.
