Determining the
level of alcohol
in my blood.

Refer to the Blood Alcohol Chart below. Align your weight with the number of drinks you have consumed and obtain the reading. You may also subtract .015 per hour as the burn-up rate. However, you should be aware that this is an estimate and the results could vary depending upon the contents of your stomach.

Estimate the percentage of alcohol in your blood by counting the number of drinks you’ve had and aligning that number with your weight.

Subtract the percentage of alcohol “burned up” during the time elapsed since your first drink.
