If you would like to know which measurement is equivalent to 1/2 gallon, you can calculate this using the following steps:
1 gallon = 128 fl. oz.
1 gallon = 16 cups
1 gallon = 4 quarts
1 gallon = 8 pints
1/2 gallon = 1/2 * 128 fl. oz. = 64 fl. oz.
1/2 gallon = 1/2 * 16 cups = 8 cups
1/2 gallon = 1/2 * 4 quarts = 2 quarts
1/2 gallon = 1/2 * 8 pints = 4 pints
Equivalent: 2 quarts.
