About Converting Pints to Imperial gallons
Pint and Imperial gallon 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. Pint is typically associated with united States (beer serving, cooking, dairy), while Imperial gallon is typically associated with united Kingdom, Canada (some contexts), and other Commonwealth countries.
Formula
imperial gallons = pints × 0.104084273079
This factor comes from each unit's defined relationship to the category's base unit: 1 pint equals 0.000473176473 base units, and 1 imperial gallon equals 0.00454609 base units, so dividing one by the other gives the direct pint-to-imperial gallon factor of 0.104084273079.
Simple example
1 pt × 0.1040842731 = 0.1040842731 imp gal
1 pint = 0.1040842731 imperial gallons.
Real-world example
10 pt × 0.1040842731 = 1.040842731 imp gal
10 pints = 1.040842731 imperial gallons.
