Gallons to Liters Converter — Free & Instant

What This Tool Does

This tool converts US liquid gallons to litres using the exact factor: 1 US gallon = 3.785411784 litres. It helps when an American car's tank size, a paint can, a water cooler or a recipe is quoted in gallons and you want the figure in litres as used in India. For UK imperial gallons the number is different (1 imperial gallon = 4.546 litres).

How to Use It

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

Example

A US car with a 15-gallon fuel tank holds about 56.8 litres. A 5-gallon water jug is about 18.9 litres, and a gallon of milk is roughly 3.79 litres.
