BLOOD-ALCOHOL CALCULATOR

The percentage of alcohol in your blood can be estimated by using the chart below. Determine your "number of drinks" you've and intersect it with the opposite "body weight" to find the percent of blood alcohol listed. It may be necessary to subtract from this number the percent of alcohol you have burned up during the time elapsed since your first drink ( .015% per hour).

The blood-alcohol chart above only provides a rough approximation of a person’s blood-alcohol concentration after a specified number of drinks. Please keep in mind that the chart is a generalization that is based on the person’s bodyweight and the volume of alcohol that is consumed. The chart assumes a complete and immediate absorption of the alcohol contained in a standard drink. This assumption is scientifically and medically incorrect. Nevertheless, the chart may be a helpful guide to estimate a person’s blood-alcohol concentration.
