Unit converter

Litres to millilitres.

Convert L to mL and mL to L. Type in either box and the other follows. A thousand to one. Medicine doses and recipe liquids are in millilitres; the bottle is labelled in litres.

Definitions

  • The litre is a thousand cubic centimetres — a cube 10 cm on each side. It is accepted for use with SI but is not itself an SI unit.
  • The millilitre is exactly one cubic centimetre. Medicine doses and recipe liquids are measured in it worldwide.
  • This conversion is exact by definition. 1 L = 1000 mL.
  • US and imperial units of the same name are different sizes. A US pint is 473 mL; an imperial pint is 568 mL. Every unit below says which system it belongs to.

How it works

One direction multiplies and the other divides by the same number, so nothing is lost by going back and forth.

The value passes through m³, the unit every other volume & capacity unit on the site is defined against, rather than a number written into this page on its own. That is why the figure here, the figure in the table above and the general volume & capacity converter always agree.

Display precision sets a maximum number of significant figures and trims trailing zeroes, so it changes what you see and never what was calculated. The editable box always holds a plain number at full working precision, so you can carry on from either side.

Common questions this answers: how many millilitres in a litre (1000), how many litres in a millilitre (0.001), and what 2 L is in millilitres (2000 mL).
