About gallons and cups

A US gallon is 4 quarts, 8 pints or 16 cups. Multiply gallons by 16 to get cups: half a gallon is 8 cups and a quarter gallon (one quart) is 4 cups.

You need this when scaling a recipe up for a crowd, making sweet tea, punch or brine by the gallon, or working out how many servings a jug holds. A UK (imperial) gallon is bigger, at 19.22 US cups, so check where a recipe comes from.
