Units involved

This is how the units in this conversion are defined:

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"

Imperial Gallons

"The imperial (UK) gallon, now defined as exactly 4.54609 litres (about 277.42 cubic inches), is used in some Commonwealth countries and was originally based on the volume of 10 pounds (approximately 4.54 kg) of water at 62 °F (17 °C). The imperial fluid ounce is defined as 1⁄160 of an imperial gallon; there are four quarts in a gallon, two pints in a quart, and 20 Imperial fluid ounces in an imperial pint."
