32 fluid ounces is the same as 4 cups. One cup is equal to 8 ounces. A pint of liquid is 16 ounces, which is two cups. The U.S. Customary System of weights and measures uses the fluid ounce to measure volume.
The inch-pound system, which is part of the U.S. Customary System, has more than 300 different units of measure. Volume is the amount of stuff that fits inside a three-dimensional space that has a boundary, like a container. Most of the time, the capacity of a container is how much it can hold.
Even though the United States has officially adopted the International System of Units, also known as the metric system, it is not used for all kinds of measurements. Like, yards are still used to measure football fields. But in the United States, most running races are measured in metres.
