Units involved

Us Dry Pints

"The pint (abbreviated as 'pt' or 'p') is a unit of volume or capacity in both the imperial and United States customary measurement systems. In both of those systems it is traditionally one-eighth of a gallon, Imperial or U.S., although measuring a different amount of liquid (an Imperial pint equals roughly 568 millilitres, or 20 Imperial fluid ounces; a U.S. pint equals roughly 473 millilitres, or 16 U.S. fluid ounces). The British pint is thus about 20% larger than the American pint (the two systems are not the same).1 US dry pint = 1⁄8 US dry gallons"

Us Gallons

"The US gallon is legally defined as 231 cubic inches, which is exactly 3.785411784 liters.[2][3] A US liquid gallon of water weighs about 8.34 pounds or 3.78 kilograms at 62 °F (17 °C), making it about 16.6% lighter than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes the US fluid ounce equal to 1⁄128 of a US gallon."
