How to calculate blood alcohol level<br>Understand what blood alcohol content (bac) means. Blood alcohol content is a measurement of the amount of alcohol in your body. So, a bac of 0.10% means 1 part alcohol for every 1000 parts of blood.
blood alcohol content is naturally always .1%
it never mentions the natural alcohol content of the body; i think the system thought always .01% was false, but didn't realize the subject changed.
