1 oz of Liquor (80 proof) or 40% by vol = 1 Glass of wine (6 oz) = 1 Beer (12 oz)
The human body metabolizes any of the above, on average, at a rate of 1 unit per hour. that means one beer, one glass of wine, or a drink with 1 oz of 80 proof liquor should be gone in one hour after finishing the drink. Factors that may affect the metabolizing of alcohol is the Height/weight of the person, How much you have had to eat, and foods that you have eaten, and most of all other drugs (legal, illegal, or even prescribed by a doctor) that may have been consumed. If you are drinking doubles, PGA, or doing shots with beer chashers, plan on getting someone else to drive, just to be safe.
