One UK alcohol unit is defined as containing 8 grams of pure alcohol, which equates to approximately 0.34 fluid ounces. This seemingly small figure is critical for understanding consumption guidelines, as the total liquid volume of a drink can be very different from its pure alcohol content.

According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), one U.S. standard drink contains 14 grams of pure alcohol. This means 20 grams of alcohol is roughly 1.4 standard drinks, which can be converted into approximately 0.86 fluid ounces.
