2 cups = 1 pint

2 pints = 1 quart

4 quarts = 1 gallon

2x2=4 so there are 4 cups in a quart and since there are 4 quarts in a gallon we do 4x4 which equals 16. So that means there are 16 cups in a gallon. There are also 128 fluid ounces in a gallon. This is measured by doing 16x8 since there are 8 fluid ounces in 1 cup.

Well here's how you could figure it out.

One cup equals 8 ounces.

Since a gallon equals 128 ounces, you divide the 128 oz. by 8 oz. (1 cup)

So 128 divided by 8 equals16.

There are 16 cups in one gallon.

There are 16 cups in one us gallon

2 cups in a pint, 2 pints in quart, 4 quarts in a gallon, therefore... 2x2x4=16 cups in a gallon.

I hope this helped and have a great day.

A gallon is 128 ounces, and a cup holds 8 ounces. Divide your gallon by your cup, and a gallon holds 16 cups.
