Why Use This Tool?

Liters to Gallons Converter turns liters into US liquid gallons instantly — useful for reading fuel economy, cooking measurements, and container sizes when the source uses metric units.

How to Convert Liters to Gallons

Divide the liter amount by 3.785411784 to convert to US liquid gallons (or multiply by 0.264172).

Note: This is the US liquid gallon. The UK (imperial) gallon is larger — 4.54609 liters — so a UK gallon figure needs a different factor (divide by 4.54609, or multiply by 0.219969).
