About Acre-Feet

An acre-foot (ac ft) = the volume covering 1 acre to 1 ft depth ≈ 1,233.5 m³ (325,851 US gal). Almost exclusively used in US water resource management. California's Lake Shasta: 4.55 million ac ft at capacity. A typical US household uses ~0.5-1 ac ft/year. Water rights on the Colorado and Sacramento rivers are traded in acre-feet. 1 ac ft ≈ 1,233.5 m³.

About Cubic Meters

A cubic meter (m³) is the SI derived unit of volume - the volume of a cube with sides of one meter - equal to 1,000 liters. It is the standard international unit for large fluid volumes, solid materials, and gas quantities. Concrete production and placement is measured in cubic meters; river discharge is reported in cubic meters per second (m³/s, or 'cumecs'); shipping container capacity is quoted in cubic meters; and natural gas is traded in standard cubic meters. An Olympic swimming pool holds 2,500 m³. One cubic meter of water has a mass of exactly 1,000 kg (one metric tonne).
