A 200 lb. female who registered a BAC of.03 has probably consumed 18 ounces of light beer within an hour. A 140 lb. male who registered a BAC of.03 has probably consumed 16 ounces of light beer within an hour. A 140 lb. female who registered a BAC of.03 has probably consumed 12 ounces of light beer within an hour.

BAC Factors Weight difference: Larger people have more blood and can consume more. Food coats lining of stomach so it does not get absorbed into blood as quickly.

BAC Factors Most alcohol is eliminated form the body through oxidation in liver. The BAC elimination rate is approximately.015 per hour. If a person has a BAC of.045 at 9pm when will he reach a zero BAC? 12am
