How the Litres to Gallons Converter Works
Litres and gallons both measure volume — litres in the metric system, gallons in the US customary. One US gallon equals about 3.78541 litres, so to convert litres to gallons you divide by 3.78541, and to convert gallons to litres you multiply. The converter also shows millilitres, quarts, pints and cups.
It works through millilitres as a common base, so the numbers stay consistent whichever unit you start from. Note these are US gallons; an imperial (UK) gallon is larger, about 4.546 litres.
gallons = litres ÷ 3.78541
