Widmark formula forensic medicine a formula used to calculate a person's blood alcohol concentration, based on the alcohol dose, alcohol distribution in body water, body weight, and rate of elimination.

Widmark's formula has some variations, so the formula is not truly a set formula (which is a pretty big problem). W being weight of the person in pounds; In most cases, the widmark formula underestimates the actual bac. This is known as the widmark formula or widmark equation. This formula calculates the bac from a past history of alcohol consumption, a form which may be called the forward widmark calculation.
