What is the relationship between Blood Alcohol Content BAC and standard drinks?

Answer 1

One standard drink (in the US*) is equal to 0.6 ounces (about 14 grams) of pure alcohol, the average amount that the human liver can metabolize in one hour. The actual amount of time depends on the health of the individual's liver, and on gender. Women do not metabolize alcohol as efficiently or rapidly as men.

The relationship of a standard drink to blood alcohol content also depends on the size of the person, their body mass index, and of course gender. The general rule of thumb is that 2 "Standard Drinks*" in the first hour will raise your BAC about to 0.07%, and one "Standard Drink" per hour thereafter will maintain that level.

*The amount of alcohol in a standard drink varies from country to country.
