The BAC calculator is only an approximation of an alcohol blood level of a person. It is NOT a concrete perfected scientific estimation (due to other factors that are not in the BAC calculator). Therefore do not rely on this estimation from the BAC calculator to be totally accurate. *Knappmann Law does not ever recommend anyone to ever operate a vehicle after drinking alcohol.
