How To Calculate Your Estimated
Blood Alcohol Content (BAC)
Showing estimated percent of alcohol in
the blood by number of drinks in relation to body weight.
This percent can be estimated by:
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: 180 lb. man - 8 drinks in 4 hours / .167% minus
(.015x4) = .107 %
