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 %

BAC Comparison Over Time

Any "average elimination" charts are simply that---for the average person.  Your rate could well be SLOWER, meaning that your BAC level would be higher than shown here, at a given time.  The purpose of this comparison chart is to demonstrate why SLOWING down consumption can be very beneficial to most drinkers, especially those who have larger body size, especially the average male drinker (versus average female of the same weight).
