The BAC calculator below shows your BAC by weight, or your estimated blood alcohol level by the number of drinks consumed in relation to your body weight. It will show you your BAC after one beer. Here is how to estimate your blood alcohol content using our drunk calculator:
1. Count your number of drinks consumed.One drink = 1 ounce of 100-proof liquor, one 5 ounce glass of table wine, or one 12 ounce bottle of regular beer.
2. Using the BAC chart below, find where “# of Drinks Consumed” and “Body Weight” intersect. This is your estimated percent of blood alcohol content.
3. Subtract from this number the percent of alcohol “burned up” during the time elapsed since your first drink. This “burn up” rate is .015% per hour. (Example: 180 lb. man – 8 drinks in 4 hours / .167% minus (.015×4) = .107 %
# of Drinks Consumed
