What Is the Difference Between Liters and Gallons?

A liter is a metric unit of volume. It is equal to 1 cubic decimeter or 1,000 cubic centimeters. A gallon is commonly used in the United States for liquid capacity, but there is more than one type of gallon.

This page uses the US liquid gallon. It is different from the larger imperial gallon used in the UK and also different from the less common US dry gallon. The exact relationship used here is 1 liter = 0.264172052358 US gallons, and 1 US gallon = 3.785411784 liters.

One reason this conversion matters is that liters are part of the metric system, while gallons are still widely used in the United States for everyday liquid measurements. Because the units come from different systems, people often need a quick conversion when reading product labels, comparing container sizes, or checking capacity in recipes, vehicles, tanks, and household storage.

For example, 1 L = 0.264172 gal, 2 L = 0.528344 gal, and 5 L = 1.320860 gal.
