Drunk Driving: Blood Alcohol Content
Showing estimated percent of alcohol in the blood by number of drinks in relation to body weight. This percent can be estimated by:
- 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).
- Use the chart below and under number of "drinks" and opposite "body weight" find the percent of blood alcohol listed.
- 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: 180 lb. man - 8 drinks in 4 hours / .167% minus (.015 x 4) = .107 %
