According to the American Medical Association, a 180-pound (82 kg)
person who drinks three 12-ounce (355 ml) bottles of beer in an hour will
end up with a BAC of about 0.06 percent. The person would reach the
same BAC by drinking three 4-ounce (120 ml) glasses of wine or three
mixed drinks if each had 1-1/2 ounces
(45 ml) of a liquor like whiskey, gin
1
or vodka.
It's the amount of alcohol that counts. For example, if the same person
drank three double martinis (3 ounces or 90 ml of liquor each) within an
hour, the person's BAC would be close to 0.12 percent. A person who
consumes food just before or during drinking will have a slightly lower
BAC level.
