How do you determine your blood alcohol concentration level?

Determining your blood alcohol concentration level (BAC)

First: Count your drinks (one drink equals 1 ounce of 100-proof liquor or one 12 ounce bottle of beer);

Second: Use the appropriate male/female chart below and under the number of drinks and opposite the appropriate body weight, find the Alchol concentration listed;

Third: Alcohol is, on average, burned up at the rate of .015 per hour. Multiply the total number of hours since your first drink by .015 and subtract this figure from the alcohol concentration level listed in the chart.

Example: 200 lb man consumes 10 drinks in 5 hours = .188 minus (5 x .015) = .113 - Blood alcohol content.
