Converting us pint to us gallon comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using us gallon, or a laboratory protocol may specify volumes in us pint that need to be measured with equipment calibrated in us gallon.
In everyday use, knowing that 5 pt = 0.625 gal and 10 pt = 1.25 gal covers most common situations. For bulk calculations, 100 pt = 12.5 gal is a useful anchor. The reverse conversion — us gallon back to us pint — uses the factor 8, so 1 gal = 8 pt.
All conversions use the internationally recognized factor of exactly 1 pt = 0.125 gal. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.
Formula: US Gallon = US Pint × 0.12499993
Multiply any us pint value by 0.12499993 to get us gallon. One us pint equals 0.12499993 gal.
Reverse: US Pint = US Gallon × 8.0000042
US pints ÷ 8 = US gallons. Exact.
8 pt = 1 gal, 4 pt = ½ gal = 1 qt.
Gallons × 8 = pints.
Serves draft beer in pint glasses, the standard US serving at 16 fl oz.

The US liquid pint is one-eighth of a US gallon, exactly 16 fluid ounces or 473.176 mL. Its name comes from Old French pinte. The pint has been a standard tavern measure since at least the 14th century.
Pints remain the defining unit for beer serving sizes in many countries. A US pint is 16 fl oz, while the UK pint is 568 mL. Blood banks measure donations in pints.
Interesting fact: 'A pint's a pound, the world around' is a US mnemonic. A pint of water weighs approximately one pound (actually 1.043 lb).
The US liquid gallon is defined as exactly 231 cubic inches, or 3.785411784 liters. It traces its origins to the Queen Anne wine gallon of 1707, which American colonies adopted.
The US gallon differs from the UK Imperial gallon by about 16.5%. This matters for fuel economy: a US MPG figure is lower than the equivalent UK MPG for the same car.
Interesting fact: The United States, Liberia, and Myanmar are the only countries using the US gallon as a primary everyday volume unit.
