Answer Wiki. The short answer is eight -- there are eight U.S. pints in a U.S. gallon, and eight British pints in a British (or Imperial) gallon, which covers any realistic situation this might come up in.
There are 16 cups in a gallon. 2 cups in a pint, 2 pints in quart, 4 quarts in a gallon, which means; 2x2x4=16 cups in a gallon. That would also be four quarts in a standard gallon. 1 US gallon = 16 US cups. 1 UK gallon = 18.18436 Metric Cups.
