About these units
Acre-Foot (US Survey) (ac*ft (US))
The US survey acre-foot differs extremely slightly from the international acre-foot due to the slight difference between the survey foot and the international foot. While the distinction is negligible in most contexts, it is important in surveying, legal water rights, and long-term hydrological accounting, especially in regions where large historical datasets were recorded using US survey measures. This variant highlights how even subtle unit differences can have major implications when dealing with huge volumes over long timescales, such as state water budgets and inter-state compacts.
Cubic Foot (ft³)
A cubic foot equals 28.31684659 liters, representing the volume of a cube one foot on each side. It is widely used in construction, real estate, natural gas metering, and HVAC systems. Room ventilation rates, airflow in ducts, and gas consumption often use cubic feet or cubic feet per minute (CFM). Storage capacity for freezers, shipping containers, and building materials also frequently uses this unit. The cubic foot's relationship to the foot makes it practical in industries where imperial length units still dominate.
