To determine your estimated BAC, follow the steps listed below.

1. Find your approximate body weight in the left hand column
2. Locate the estimated total BAC under the column corresponding to the number of drinks consumed
3. Determine the number of hours since you started drinking
4. For every hour, subtract 15 mg% from the total BAC estimated

Example
Calculate the BAC of a 150 pound man who has had 4 drinks in 2 hours. From the chart, a BAC of 116 mg% is observed in the row labled 150 Lbs under "Drink column" 4. From this figure of 116, subtract 30mg% for the two-hour elimination period. This gives us a BAC of 116 minus 30 (86 mg%).
If you weigh more than your ideal weight, the difference may be due to the fact that you have more fatty tissue. Consequently, your BAC will be higher and the impairing effects of alcohol will be greater.

1 drink = 1.5 volume oz. of rum, rye, scotch, brandy, gin, vodka, etc.
1 drink = 1, 12oz. bottle of normal strength beer
1 drink = 3 oz. of fortified wine
1 drink = 5 oz. of table wine
100 mg% = 0.10% BAC = 1.0% PROMILLE
