Intragalactic Lawyer's Calculation of BAC – a web page for calculating Blood Alcohol Concentration for non-Terran beverages and species.
Blood Alcohol Concentration is not the same as concentration of alcohol in the whole body. Not all of the body holds alcohol. Alcohol is not distributed uniformly throughout the body. The parts of the body that aren't blood, organs, and muscles don't hold much alcohol. Fat and bone don't absorb much. Terran females have less body water. Obese terrans have less. Some species such as Klingons and Cardassians have more bone, but they also have more muscle. Klingon females have more fat and bone. You have to apply the Widmark r factor to adjust. For Terran males the Widmark r factor is between 0.50 and 0.90 with an average of 0.70. For Terran females the Widmark r factor is 0.45 to 0.63 with an average of 0.60. The form below assumes the following average Widmark r factors. If you have scientific data or theory tending to show any inaccuracy in these body water averages your input is welcome.
