Blood Alcohol Content (BAC) Calculator Robert A. Thornton Jr. Attorneys Denton Maryland

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 or 1 12-ounce bottle of beer.)
Use the chart below and under number of "drinks" and poosite "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 lbs. man - 8 drinks in 4 hours

.167% minus (.015 x 4) = .10%
