### What is a Gallon?

A gallon is a unit of volume, larger than a pint, liter, and fluid ounce, but smaller than a cubic foot and a US barrel. It’s commonly used in daily life, with 1 gallon equal to 4 quarts, 8 pints, or 16 cups. This volume is approximately the daily water intake for an average adult male.
