Blood Alcohol Content or B.A.C.

The total ratio of alcohol to blood volume is known as the Blood Alcohol Content (B.A.C.) or the Blood Alcohol Level (B.A.L.).

Alcoholic Beverage Serving Sizes 

Even though drinks come in different sizes, a standard drink contains roughly 14 grams of pure alcohol. That amount can be found in the following kinds of beverages.

·         Regular Beer – 12 fluid ounces of 5% alcohol

·         Malt Liquor – 8-9 fluid ounces of 7% alcohol

·         Table Wine – 5 fluid ounces of 12% alcohol

·         80 Proof Spirits – 1.5 fluid ounces of 40% alcohol

Calculating Blood Alcohol Content 

A person’s estimated Blood Alcohol Content is based on the number of servings of alcohol consumed, body weight and whether the person is male or female.t

How long does it take for alcohol to process through the system? People only burn about .016% off their Blood Alcohol Level each hour. There is no way to sober up more quickly. Drinking coffee, exercising, vomiting or taking a cold shower won't help a person sober up.
