Liters to Milliliters formula
To convert liters to milliliters, multiply by 1000.
mL = L × 1000
Put another way, one liter is exactly 1,000 milliliters.
Why this factor: the liter and the milliliter are both defined against the liter, so dividing one definition by the other gives 1000 directly. Both definitions are set out in full below.
To go the other way, divide by 1000 — or use the Milliliters to Liters converter, which is the same calculation reversed.
Worked example
Start with 8 L. Multiply by 1000 to get 8000 mL.
8 L × 1000 = 8000 mL
The converter above does this for any value you type, in either direction.
What is a liter?
A liter is the everyday metric unit of volume, equal to the space in a 10 cm cube.
Definition: Exactly one cubic decimeter, so exactly 0.001 cubic meter. Accepted for use with SI but not an SI unit itself.
Where it is used: Fuel, beverages, engine displacement, and recipe volumes across the metric world.
What is a milliliter?
A milliliter is one thousandth of a liter, and is exactly the same volume as a cubic centimeter.
Definition: Exactly 0.001 liter, which is exactly 1 cm³.
Where it is used: Medicine doses, cosmetics, recipe quantities, and laboratory work.
Worth knowing: 1 mL = 1 cm³ = 1 cc exactly, so these three units are interchangeable.
Liters vs Milliliters
The liter and the milliliter belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
