When and where it was developed

Metric system, 1795.

Metric / SI

Liter

What is a liter?

The liter is a metric unit of volume equal to one cubic decimeter (0.001 m³). It is the everyday metric volume unit.

Origin of the liter

Introduced in France in 1795; redefined in 1964 as exactly one cubic decimeter.

Where it is used

The world's common unit for beverages, fuel, and household liquids.

When and where it was developed

France, 1795; CGPM 1964.

Cubic Kilometer to Liter conversion formula

The relationship between cubic kilometers and liters:

1 km³ = 1e+12 L
1 L = 1e-12 km³

To convert cubic kilometers to liters, multiply the value in cubic kilometers by 1e+12. To reverse, multiply liters by 1e-12.
