Cups in a Gallon: Gallons to Cups Converter

There are 16 cups in a US gallon. A half gallon is 8 cups, a quarter gallon (1 quart) is 4 cups and an eighth of a gallon (1 pint) is 2 cups. Each cup is 1/16 of a gallon, or 0.0625 gallon.

A cup is 1/16 of a gallon, which is 0.0625 gallon. Two cups are 1/8 gallon, 4 cups are 1/4 gallon and 8 cups are 1/2 gallon. Divide the cups by 16 to get gallons.

No. 4 cups make a quart, which is a quarter of a gallon. A half gallon is 8 cups, or 2 quarts.

No. 12 cups are 3/4 of a gallon (0.75 gallon), which is 3 quarts. A gallon needs 16 cups, so you would add 4 more cups.

A half gallon is 8 cups, whether it holds milk, juice, ice cream or buttermilk, because the unit measures volume. Two quart containers make a half gallon.

A gallon is 4 quarts, so 16 cups / 4 gives 4 cups in each quart. That is also 8 pints. Two quarts are 8 cups, which is why half a gallon is 2 quarts.

2 quarts are 8 cups, because a quart is 4 cups. Three quarts are 12 cups and four quarts are 16 cups, a full gallon.

A pint is 2 cups, so 8 pints are 16 cups, the same as 1 gallon. A pint is also 16 fluid ounces.

A gallon is 128 fluid ounces, a half gallon is 64, a quart is 32, a pint is 16 and a cup is 8. That holds for a gallon of water, milk or ice cream alike, because the unit measures volume. A cup of 8 fluid ounces is 1/16 of the 128 in a gallon. The ounces in a gallon converter and the ounces in a quart converter go into more detail.

It takes 16 glasses of 8 fluid ounces, because a gallon is 128 fluid ounces and each such glass is exactly one cup. With 12 oz glasses a gallon fills 10 2/3 glasses, and with 16 oz glasses 8.

A gallon holds about 7.57 bottles of 16.9 fluid ounces, since 128 / 16.9 = 7.57. Eight such bottles hold 135.2 fluid ounces, a little more than a gallon. A 500 mL bottle is 16.9 fluid ounces, so the same count applies to it.

It serves 36 cups of 8 fluid ounces. Multiply the gallons by 16: 2.25 × 16 = 36. That is also 9 quarts or 288 fluid ounces.

The US system uses a gallon of exactly 231 cubic inches, which is 3.785 liters and 16 cups of 236.59 mL. The British imperial system uses a larger gallon of 4.546 liters, about 20% more, which holds about 19.2 US cups. The metric system counts in liters and milliliters. Cups differ too: the US nutrition label cup is 240 mL and the metric cup of Canada, Australia and New Zealand is 250 mL.

A liter is 1.057 US quarts, or about 4.23 US cups. A US quart is slightly smaller than a liter, at 0.946 liter, and a gallon is 3.785 liters.
