There are 8 pints in a US gallon. Pints = gallons × 8; the same gallon is 4 quarts or 16 cups.

How many pints are in a gallon

A US gallon holds exactly 8 pints. The chain of US liquid measure is simple: a gallon is 4 quarts, each quart is 2 pints, so a gallon is 8 pints. From there, each pint is 2 cups and each cup is 8 fluid ounces, which makes a gallon 16 cups or 128 fluid ounces.

To convert gallons to pints, multiply by 8. Half a gallon is 4 pints; two gallons is 16 pints. The relationship is a definition, so it is exact for any liquid.

US pints, not UK pints

This tool uses US measure, where a gallon is 8 US pints of 16 fluid ounces each. The UK also puts 8 pints in its gallon, but the imperial pint is larger at 20 imperial fluid ounces, and the imperial gallon is about 20 percent bigger than the US gallon.

So '8 pints per gallon' is true in both systems, but a US gallon and a UK gallon are not the same size. Match the system before you convert.

How it’s calculated

US customary volume, exact by definition: 1 gallon = 8 pints = 4 quarts = 16 cups = 128 fluid ounces. Pints = gallons × 8, quarts = gallons × 4, cups = gallons × 16, fluid ounces = gallons × 128.

Uses the US liquid gallon and pint. Imperial (UK) pints and gallons are larger, so do not mix the two systems.

Common mistakes

  • Dividing by 8 instead of multiplying — a gallon is bigger than a pint, so the pint count rises.
  • Mixing a US gallon with imperial pints; the UK pint is about 20 percent larger.
  • Confusing dry and liquid measure; this tool is liquid volume.
  • Reading fluid ounces as weight ounces.

Frequently asked questions

How many pints are in a gallon?

There are exactly 8 pints in a US gallon. To convert gallons to pints, multiply the gallon count by 8.

How many pints in a half gallon?

Four pints. Half of 8 is 4, which is also 2 quarts or 8 cups.

What is the formula for gallons to pints?

Pints = gallons × 8. For quarts multiply by 4, for cups by 16, and for fluid ounces by 128.

Is a US gallon the same as a UK gallon?

No. Both hold 8 pints, but the imperial (UK) pint and gallon are larger, so a UK gallon is about 20 percent bigger than a US gallon.
