8 US pints = 1 US gallon. Gallons = pints ÷ 8; the same pint is 2 cups or 16 fluid ounces.
Eight pints to the gallon
US liquid measure stacks in twos and fours. Two cups make a pint, two pints make a quart, and four quarts make a gallon — so eight pints fill one gallon. To convert pints to gallons you simply divide by 8. One pint is 0.125 gallon, four pints is half a gallon, and sixteen pints is two gallons.
Because these are fixed definitions, the result is exact for any liquid. No density or substance is involved; a pint of water and a pint of oil are the same 0.125 gallon of space.
US and UK pints are not the same
This converter uses the US liquid pint of 16 fluid ounces (473 mL). A UK pint is larger at 20 imperial fluid ounces (568 mL), and a UK gallon still holds 8 UK pints. So the 'divide by 8' rule holds within each system, but you cannot mix a US pint count with a UK gallon.
When a recipe or pub measure looks off, check which pint it means before converting.
How it’s calculated
US customary volume, exact by definition: 1 gallon = 8 pints = 4 quarts = 16 cups = 128 fluid ounces. Gallons = pints ÷ 8, quarts = pints ÷ 2, cups = pints × 2, fluid ounces = pints × 16.
Uses the US liquid pint (16 fl oz). UK pints are 20 imperial fl oz, so do not mix systems.

Common mistakes
- Multiplying by 8 instead of dividing — pints are smaller than gallons, so the gallon count drops.
- Mixing a US pint count with an imperial gallon; the UK pint is about 20 percent larger.
- Confusing dry pints with liquid pints; this tool is liquid measure.
- Reading fluid ounces as weight ounces.
