Which measurement is equivalent to 5 quarts?25 cups
40 fl. oz.
10 pints
1.5 gallons

Answers

If you would like to know which measurement is equivalent to 5 quarts, you can calculate this using the following steps:

1 quart = 4 cups
1 quart = 2 pints
1 quart = 32 fl. oz.
1 quart = 0.25 gallons

5 quarts = 5 * 4 cups = 20 cups
5 quarts = 5 * 2 pints = 10 pints
5 quarts = 5 * 32 fl. oz. = 160 fl. oz.
5 quarts = 5 * 0.25 gallons = 1.25 gallons

Equivalent: 10 pints.
