According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), a standard U.S. drink contains approximately 0.6 ounces of pure alcohol.

According to the Alcohol and Tobacco Tax and Trade Bureau (TTB), the United States defines proof as twice the percentage of alcohol by volume (ABV). While the two measurements are intrinsically linked, proof is not the same as volume; instead, it is a way of expressing the concentration of alcohol within a given volume of liquid.

According to the Centers for Disease Control and Prevention (CDC), a standard drink in the United States contains 0.6 ounces of pure alcohol. A 1.5-ounce serving of 80-proof liquor, such as vodka, is the established equivalent of one standard drink. Understanding this helps in tracking consumption for health and safety.
