How to calculate blood alcohol level
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.

It is often used for legal or medical purposes, like when determining if you've had too much to drink and drive. A bac of 0.08%, often the legal level, indicates that you have 80 mg of alcohol per 100ml of blood in your body.
