What Are the Imperial Units for Volume?

This entry uses the imperial system of measurement. For the metric system, click here.

Volume measures how much can fit inside of something. How much water is in your bathtub? How much milk is in a carton? How big is the trunk of your car?

Volume dealing with fluids is measured in fluid ounce (fl oz), cup, pint (pt), quart (qt) and gallon (gal).

Bottles and other small containers measure their fluids in fluid ounces. Most small soda bottles contain $20$ fl oz or $24$ fl oz, while a soda can is only $12$ fl oz.

One cup is $8$ fl oz and is often used when measuring volume for cooking and baking. Cups are also often used for non-fluids such as sugar or flour.

One pint is two cups and is mostly used as a measure of alcoholic beverages, but sometimes other bottles like milk and soda.

One quart is two pints and one fourth of gallon. Milk is often bought in quarts.

One gallon is four quarts and 16 cups. Gasoline and large containers of milk are bought in gallons.

Below, you see the connection between different units of volume. It is expected of you to be able to convert one unit into another.
