How to Calculate Your Estimated Blood Alcohol Content (BAC)

This chart will help you estimate the percentage of alcohol in the blood using the number of drinks in relation to your body weight. A Blood Alcohol Content (BAC) of .08 or more is legally intoxicated in Texas. Follow these steps:

1. Count your drinks (1 drink equals 1 ounce of 100-proof liquor, one five ounce glass of table wine or one 12-ounce bottle of regular beer).
2. Use the chart below and under number of Drinks and opposite Body weight find the percent of blood alcohol listed.
3. Subtract from this number the percent of alcohol burned up during the time elapsed since your first drink. This figure is .015% per hour.

   Example: 190 lbs. man – 6 drinks in 3 hours / .119% minus .045 (.015 x 3) = .074%)
