According to U.S. health guidelines, a standard drink contains 0.6 ounces of pure alcohol. It is a well-known fact among beverage professionals that a 1.5 oz serving of 80 proof spirits fits this definition perfectly, revealing exactly how much alcohol is in a 1.5 oz 80 proof drink.

According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), one standard 12-ounce beer is considered equivalent to one 1.5-ounce shot of 80-proof (40% ABV) rum, as both contain roughly 0.6 fluid ounces of pure alcohol. However, this simple 1:1 ratio is a baseline, and the actual equivalence depends heavily on the specific alcohol by volume (ABV) of both beverages.
