ONLY 2 CASES OF BEER AND THEY SAID I WAS DRUNK
How to estimate your blood alcohol level
When I was younger, I could remember anything,
whether it had happened or not.
MARK TWAIN
You can estimate the percent of alcohol in the blood by the number of drinks in relation to body weight. You should remember, this is just an estimate. Many factors such as food consumption, prior exposure to alcohol, medical issue, gender biases, and time of consumption can change the calculations up or down. To make an estimate:
- Count your drinks (1 drink equals 1 ounce of 100-proof liquor, one five – ounce glass of table wine or one 12-ounce bottle of regular beer).
- Use the following chart and under number of “drinks” and opposite “body weight” find the percent of blood alcohol listed.

Subtract from this number the percent of alcohol “burned up” during the time elapsed since your first drink. This figure is .015% per hour. (Example: 180 lb. man has 8 drinks in 4 hours / .167% minus (.015×4) = .107 %)
