Units explained

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.

Metric / SI

Cubic Kilometer

What is a cubic kilometer?

A cubic kilometer is the volume of a cube one kilometer on each side, equal to 1,000,000,000 cubic meters.

Origin of the cubic kilometer

Derived by cubing the kilometer, an SI length unit standardized under the metric system from 1795.

Where it is used

Used for very large volumes such as lakes, reservoirs, glaciers and oceanic water budgets.

When and where it was developed

Metric system, 1795.

Liter to Cubic Kilometer conversion formula

The relationship between liters and cubic kilometers:

1 L = 1e-12 km³
1 km³ = 1e+12 L

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

Step-by-step: convert liters to cubic kilometers

  1. Write down the value in liters (L).
  2. Multiply that value by the factor 1e-12.
  3. The product is the equivalent value in cubic kilometers (km³).
  4. To reverse, multiply the cubic kilometer value by 1e+12.

Worked examples

Example 1 — Convert 1 L to km³:
1 × 1e-12 = 1e-12 km³

Example 2 — Convert 100 L to km³:
100 × 1e-12 = 1e-10 km³

Real-world example — Ruler-scale measurements

A 30-liter school ruler converts cleanly to cubic kilometers — useful when buying a desk accessory from a retailer whose product specs use a different unit.

30 L × 1e-12 = 3e-11 km³

Real-world example — Hardware-scale dimensions

A 10-liter fastener or component is about as long as a thumbnail. Mechanics and DIY enthusiasts convert between liters and cubic kilometers daily when mixing metric and imperial tools.

10 L × 1e-12 = 1e-11 km³

Real-world example — Postcard and small-object dimensions

A postcard is about 5 liters wide. Converting to cubic kilometers is essential for international postal addressing forms that ask for dimensions in different units across countries.

5 L × 1e-12 = 5e-12 km³
