Cubic Kilometer
A cubic kilometer (km^3) is a unit of volume representing the volume of a cube with edges of one kilometer in length.
History/Origin
The cubic kilometer has been used in scientific and engineering contexts to measure large volumes, especially in geology, hydrology, and environmental sciences, as a convenient unit for expressing vast quantities of water, earth, or other materials.
Current Use
Today, the cubic kilometer is primarily used in fields such as hydrology to quantify large-scale water volumes, like reservoirs and aquifers, and in geology and environmental science to measure large volumes of earth or other substances.
Acre-Foot (Us Survey)
An acre-foot is a unit of volume commonly used in the United States to measure large quantities of water, equivalent to the volume of one acre of surface area to a depth of one foot.
History/Origin
The acre-foot originated from the traditional use of acres and feet as units of land and water measurement in the United States, primarily for irrigation and water resource management, becoming standardized in the early 20th century.
Current Use
The acre-foot is primarily used in water resource management, including measuring reservoir capacities, water rights, and irrigation supplies within the United States.
