About Liters and Gallons
Liters (L): One cubic decimeter, or 1,000 cubic centimeters; one liter of water at standard conditions weighs almost exactly one kilogram, a coincidence that made the unit popular for everyday volume measurement. Common uses: Beverage container sizes, fuel (especially outside the US, where fuel is sold by the liter), engine displacements, and large-volume cooking and chemistry.
Gallons (gal): The US gallon (3.785 L) descends from Queen Anne's 1707 wine gallon; the UK switched to a larger imperial gallon (4.546 L) in 1824, but the US kept the original definition. Common uses: US fuel sales, US milk packaging, lawn and garden chemicals, swimming pool volumes, and aquariums.

When this conversion matters
Converting between liters and gallons comes up wherever volume measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
