A gallon is a unit of volume commonly used in the United States for measuring liquids, and its size can be broken down into smaller units.
In the U.S. customary system:
- 1 gallon (US) = 4 quarts
- 1 quart (US) = 32 fluid ounces
- Therefore, 1 gallon (US) = 4 quarts × 32 fluid ounces per quart = 128 fluid ounces.
So, there are 128 fluid ounces in a U.S. gallon.
It’s important to note that in other countries like the UK, a gallon is larger and differs from the U.S. gallon, but for U.S. measurements, 1 gallon equals 128 ounces.
