Definition: A cubic kilometer (symbol: km³) is the volume of a cube with sides of one kilometer. It is an extremely large unit equal to one trillion liters.
History/origin: The cubic kilometer became useful in geography, hydrology, and earth science where lakes, glaciers, and atmospheric volumes are too large for smaller units.
Current use: Cubic kilometers are used for reservoirs, oceans, ice sheets, volcanic material, and other very large natural volumes.
Definition: The imperial gallon is the British gallon standard. It is larger than the US gallon and is defined as exactly 4.54609 L.
