Litre (L)

1 L = 1,000 mL

Definition. A cubic decimetre (0.001 m³), the SI-accepted metric unit of volume

History and origin

The litre was introduced in France in 1795 as a unit of volume, defined as one cubic decimetre. It is not an SI base unit but is accepted for use with the SI.

Current use

Litres measure drinks and bottles, fuel and engine sizes across the metric world, and appear on beverage containers almost everywhere.

Where people use this

Millilitres: recipes, medicine doses, cosmetics. Litres: drinks and bottles, fuel, engine sizes. 500 mL is 0.5 L.

How we know this is right
The factor is fixed by the standards that define the units, not chosen — so it is exact, not a measurement:
1 L = 1,000 mL, so 1 mL = 1 ÷ 1,000 = 0.001 L.

Every value is carried to full double precision; the display is rounded.

Both units are defined in BIPM SI Brochure (2019); the litre is an SI-accepted unit (1 L = 1 dm³).
