How Many Pints in a Gallon
A pints-in-a-gallon conversion page translates liquid volumes between pints and gallons. In both the US Customary and Imperial (UK) systems, a gallon contains exactly 8 pints. However, because the US fluid ounce is slightly larger than the Imperial fluid ounce and a US pint contains 16 ounces while an Imperial pint contains 20, the physical volumes of the two systems differ by about 20%.

How it works
In both the US and British measurement systems, a gallon is divided into 4 quarts, and each quart contains 2 pints:
1 Gallon (gal) = 8 Pints (pt)
Comparing US Customary and UK Pints and Gallons
Although both systems define a gallon as containing 8 pints, the physical size of the containers differs.
A US liquid gallon is defined as 231 cubic inches, making a US pint 16 fl oz (473.18 mL). A British Imperial gallon is defined as the volume of 10 lbs of water, making the Imperial pint 20 fl oz (568.26 mL).
