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.
Since 1 pint contains 96 teaspoons and 32 tablespoons, 1 gallon contains 768 teaspoons and 256 tablespoons. One pint equals 16 fluid ounces, and 1 gallon equals 128 fluid ounces. One pint equals 2 cups, so 1 gallon equals 16 cups. Two pints make up 1 quart, and 4 quarts make up 1 gallon. One U.S. gallon is equal to 3.79 liters.
