Know your blood alcohol content (BAC)
Understanding BAC is key to understanding how alcohol affects your body and the serious danger zones of alcohol poisoning. BAC measures the ratio of alcohol in the blood. A BAC of .10 means one part alcohol in 1000 parts of blood.
To calculate your BAC, select the appropriate chart--for males or for females--then find the row closest to your weight. Then select the number of drinks consumed. When the two columns intersect you'll see your approximate BAC level if you drink that number of drinks in one hour.
