Liter to Gallon Converter

Convert volumes between liters and US gallons quickly and accurately. This converter supports conversions both directions — liters to gallons and gallons to liters — and updates results instantly as you type. Whether you're cooking, measuring liquids for a project, or simply curious about volume conversions, this tool provides the precision you need.

How it Works

The tool converts the input volume to a base unit (liters) and then converts that base value to the target unit. Using a base unit avoids direct pairwise conversion logic and reduces rounding inconsistencies. You simply enter the amount you want to convert, and the results will instantly update to reflect the equivalent volume in gallons.

Result = (Value × From Unit Factor) / To Unit Factor
