Gallon is a unit of measuring capacity or volume. Its used for measuring liquid amounts just as pounds is used for measuring weight. Gallons are commonly used in United States. It is the customary measurement system volume unit.

4 quarts make a gallon. To convert quarts into gallons, you divide the number of quarts by 4. For instance, if you have 32 quarts and you want to get the number of gallons, you divide 32 by 4 to get 8 which is the number of gallons. To get back gallons to quarts you multiply the number of gallons by 4.

Gallons also relate to other capacity units like this; there are 16 cups of liquid in a gallon, 8 pints in a gallon, and 4 quarts in a gallon. That’s easier to remember.

A quart has 4 cups and 2 pints. A pint has 2 cups.

Let’s see how in metric system how they relate. Remember in metric system which is the most used in the world Liters is the standard unit for measuring capacity. 1 quart is equal to 0.94635294549 Liters. The volume of quart is much more than that of a liter though by a minute margin. Liquid volume is also measured in cubic centimetres or meters.
