Volume is the category where the US and imperial systems diverge most damagingly. Gallons, quarts, pints and fluid ounces all exist in two sizes that differ by up to 20%, and nothing in the name warns you which one a figure uses. Recipes, fuel economy figures and container capacities all cross borders regularly, so it is worth checking which system a source is using before converting rather than after.
liters to ml formula
To go the other way, use liter = milliliter ÷ 1,000.
About these units
A litre is exactly one cubic decimetre, or 1,000 cubic centimetres. One litre of water weighs almost exactly one kilogram, which is not a coincidence.
A millilitre is exactly one cubic centimetre. Because one millilitre of water weighs one gram, the unit doubles as a rough mass measure in the kitchen.
Liter is also written litre, litres, liters and ltr. Milliliter is also written millilitre, millilitres, milliliters and cc.
