Pints to Gallons Converter

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.

How to use the Pints to Gallons Converter

1. Type the number of US pints into the US pints field. Decimals such as 4 are fine.
2. Read the answer in US gallons. It updates as you type, with no button to press. The same amount is also shown in US qt, L, UK pt.
3. To go from US gallons back to US pints, type into the US gallons field instead. Every field also has a unit menu with all 27 volume units, for example L, mL, cL, dL, m³, cm³ (cc), µL, UK gal, US dry gal, US qt.

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, for example 16 US pt is 2 US gal.

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.
