In particular for cases involving heavy drinking over a long period of time, the Widmark Equation overestimates the BAC by up to 50-100% or more. At lower amounts of alcohol consumed, the Widmark equation is very reliable.

How do you calculate promille?

In Germany, the alcohol levels are expressed as promille, in other words g/1000 l. In order to express c in g/1000 g, the BAC (g/100ml), is multiplied by 10 and divided by 1,056. Alcohol is water-soluble; the water content of any organ or tissue will therefore determine how much alcohol can dissolve in it.

What is BAC and how is it measured?

A BAC describes the amount of alcohol in a person’s blood, expressed as weight of alcohol per unit of volume of blood. For most legal purposes, however, a blood sample is not necessary to determine a person’s BAC. It can be measured more simply by analyzing exhaled breath.

It is never okay to drive after drinking regardless of what you may calculate as your BAC using this formula.
