Liters to Gallons Converter — Free & Instant

What This Tool Does

This tool converts litres to US liquid gallons using the exact factor: 1 US gallon = 3.785411784 litres. Indian fuel is sold by the litre, but US fuel prices, car tank sizes and mileage figures (mpg) are all in gallons, so the conversion matters when comparing fuel economy or following US recipes, aquarium guides and water-storage specs. Note that this is the US gallon; the UK imperial gallon is larger (4.546 litres) — see why the two differ.

How to Use It

Type your value into the field (the tool is pre-set for this conversion).
Press Convert.
Your result appears instantly. The Category, From and To dropdowns still work if you want a different unit pair.

Example

A 40-litre petrol tank holds about 10.57 US gallons. If your car does 15 km per litre, that is about 35 mpg (US) — useful when comparing against the mpg figures in American car reviews.
