Cubic kilometer (km³)
A cubic kilometer (symbol: km³) is a decimal metric unit of volume representing a cube with edges measuring one kilometer. Equal to one billion cubic meters (1,000,000,000 m³) or one trillion liters, this large-scale SI derived unit is utilized in geosciences, hydrology, and planetary astronomy. It measures immense natural volumes such as global ocean capacities, total atmospheric layers, volumetric ice sheet reserves in Greenland and Antarctica, and major volcanic ejecta.
