Blood Alcohol Content is the amount of alcohol in the bloodstream that is measured by grams of alcohol per 100 grams of blood.

Here is an example, if you have 8 grams of alcohol in 10,000 grams of blood, that’s 0.08% BAC. The legal driving limit in the USA is also 0.08% BAC if you’re over the age of 21. Calculating BAC has many variables, so take this calculator as an approximation.

Our website is geared towards providing safe drinking tips from Lawyers, Doctors and people who love drinking. We have articles about understanding BAC, as well as fun places to go for a few drinks. We have breathalyzers for sale for those who are looking to purchase a professional breathalyzer. It’s important to remember you shouldn’t drive a car while intoxicated, if you hurt someone – they can hire a personal injury lawyer and sue you.
