About Converting Gallons to Pints
Gallon and Pint appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Gallon is typically associated with united States (fuel, beverage, and liquid measurement), while Pint is typically associated with united States (beer serving, cooking, dairy).
Formula
pints = gallons × 8
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon equals 0.003785411784 base units, and 1 pint equals 0.000473176473 base units, so dividing one by the other gives the direct gallon-to-pint factor of 8.
Simple example
1 gal × 8 = 8 pt
1 gallon = 8 pints.
Real-world example
10 gal × 8 = 80 pt
10 gallons = 80 pints.

History of the Gallon
The US gallon descends from the English wine gallon of 231 cubic inches, a standard used for measuring wine in medieval and early modern England, which the American colonies inherited and retained even after England moved to a different imperial gallon in 1824.
England's 1824 Weights and Measures Act replaced the old wine gallon with a new imperial gallon (based on 10 pounds of water), but the US kept the older 231-cubic-inch definition — which is why the US gallon (3.785 L) and the imperial gallon (4.546 L) differ by about 20% today.
