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 100proof liquor, one
five ounce glass of table wine or one 12ounce 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 %
