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.
Cubic Foot
A cubic foot is the volume of a cube one foot on a side (28.3168 L).
Derived by cubing the international foot (0.3048 m).
Used for natural gas, refrigerators, shipping and HVAC.
1959 yard agreement.
