Gallon (gal)
A gallon (symbol: gal) is a unit of volume historically used in Western trade and retained today in US customary and British imperial measurement systems. The US liquid gallon is defined as exactly 231 cubic inches (approximately 3.785 liters), based on the medieval English wine gallon. Conversely, the imperial gallon, defined in 1824 as the volume of 10 pounds of distilled water, equals approximately 4.546 liters, making the two distinct standards despite sharing a name.
