gallons (gal)
The gallon is a unit with a split personality. The US Gallon (approx. 3.785 L) is based on the pre-1824 English wine gallon. The Imperial Gallon (approx. 4.546 L) used in the UK is about 20% larger. This divergence happened when Britain updated its standards in 1824, but the newly independent US stuck with the old wine gallon. Today, the US gallon is the standard for fuel and milk in the United States.

liters (L)

Although technically a 'non-SI unit accepted for use with the SI,' it is the most common volume unit worldwide for beverages, fuel, and trade. It bridges the gap between small mL quantities and large cubic meter volumes.
