How Many Quarts Are in a Gallon?

Here is how a gallon breaks down:

• 1 gallon = 4 quarts
• 1 quart = 2 pints, so 1 gallon = 8 pints
• 1 pint = 2 cups, so 1 gallon = 16 cups
• 1 gallon = 128 US fluid ounces

Just keep in mind the two gallon sizes are different volumes even though both hold 4 quarts:

• US gallon ≈ 3.785 liters
• Imperial (UK) gallon ≈ 4.546 liters

The number of quarts stays the same (4) — only the total volume changes.
