Eight pints make a gallon. Dairy and paint are sold in both sizes, and the ratio is the same in the U.S. and imperial systems.

This page converts only US pt ⇄ US gal. Need a different unit? Use the general volume converter, where you can choose any “from” and “to” unit.

How it works

Both units measure volume, so they are always in the same ratio: one US pint equals 0.125 US gallons. The calculator multiplies the number of US pints you type by 0.125 to give US gallons, and when you type into the US gallons field it divides by the same factor to give US pints. Because the ratio never changes, doubling the US pints always doubles the US gallons. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).

How to convert US pints to US gallons

1. Write down the value in US pints, for example 8 US pt.
2. Multiply by the conversion factor 0.125 (because 1 US pint = 0.125 US gal).
3. 8 × 0.125 = 1 US gal.
4. To go back from US gallons to US pints, divide by 0.125 – or multiply by 8.
