Volume converter: litres, millilitres and gallons
Recipes, fuel quantities, aquariums and engineering capacities can use litres (L), millilitres (mL), cubic metres (m³), fluid ounces and gallons. This calculator uses US gallons, which differ from imperial gallons.
Common volume conversion examples
- 1 litre = 1,000 millilitres
- 1 cubic metre = 1,000 litres
- 1 US gallon = 3.785411784 litres
- 1 US fluid ounce ≈ 29.57353 millilitres
How to convert litres to millilitres
Multiply litres by 1,000 to find millilitres; divide millilitres by 1,000 for litres. If you see “gallon” in a source, confirm whether it means a US or imperial gallon.
Can litres be converted directly to kilograms?
Not without knowing the material’s density. One litre of water has a mass of roughly one kilogram under ordinary conditions, but oils and other liquids differ.
