Units explained
Cubic Kilometer
A cubic kilometer is the volume of a cube one kilometer on each side, equal to 1,000,000,000 cubic meters.
Derived by cubing the kilometer, an SI length unit standardized under the metric system from 1795.
Used for very large volumes such as lakes, reservoirs, glaciers and oceanic water budgets.
Metric system, 1795.
Liter
The liter is a metric unit of volume equal to one cubic decimeter (0.001 m³). It is the everyday metric volume unit.
Introduced in France in 1795; redefined in 1964 as exactly one cubic decimeter.
The world's common unit for beverages, fuel, and household liquids.
France, 1795; CGPM 1964.

Step-by-step: convert cubic kilometers to liters
- Write down the value in cubic kilometers (km³).
- Multiply that value by the factor 1e+12.
- The product is the equivalent value in liters (L).
- To reverse, multiply the liter value by 1e-12.
Worked examples
Example 1 — Convert 1 km³ to L:
1 × 1e+12 = 1e+12 L
Example 2 — Convert 100 km³ to L:
100 × 1e+12 = 1e+14 L
