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 Feet
A cubic foot (ft³) is the volume of a cube with sides of one foot (30.48 cm), equal to approximately 28.317 liters. It is widely used in US construction, HVAC engineering, natural gas distribution, and real estate. Natural gas consumption is billed in cubic feet (Ccf = 100 ft³, Mcf = 1,000 ft³); refrigerator, oven, and storage compartment capacity are rated in cubic feet; and concrete or soil orders are quoted in cubic yards or cubic feet. One cubic foot of water weighs approximately 62.4 pounds. Air conditioning units are sized in BTU per hour for room volumes measured in cubic feet.
