What is the difference between a pint a quart and a cup?

A pint

In US measure, 1 pint = 2 cups And 1 cup = 0.5 pint.

There are 16 US fluid ounces, 2 cups in 1 US pint (473.2 ml).

Although there are 20 Imperial fluid ounces in 1 Imperial pint (568.3 ml), the Imperial system does not have cups, so it is best to use half pints.
