Cubic foot

== Symbols and abbreviations ==

The IEEE symbol for the cubic foot is ft3. The following abbreviations are used: cubicfeet, cubicfoot, cubicft, cufeet, cufoot, cuft, cu.ft, cuft, cbft, cb.ft, cbft, cbf, feet, foot, ft, feet/-3, foot/-3, ft/-3. Larger multiples are in common usage in commerce and industry in the United States: • CCF or HCF: Centum (Latin hundred) cubic feet; i.e., • Used in the billing of natural gas and water supply delivered to households. • MCF: Mille (Latin thousand) cubic feet; i.e., • MMCF: Mille mille (= million) cubic feet; i.e., • MMCFD: MMCF per day; i.e., • Used in the oil and gas industry. • BCF or TMC: Billion or thousand million cubic feet; i.e., • TMC is usually used for referring to storage capacity and actual storage volume of storage dams. • TCF: Trillion cubic feet; i.e., • Used in the oil and gas industry. ==Cubic foot per second and related flow rates==

The IEEE symbol for the cubic foot per second is ft3/s. The following other abbreviations are also sometimes used: • ft3/sec • cu ft/s • cfs or CFS • cusec • second-feet The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second. Cusec is a unit of flow rate, used mostly in the United States in the context of water flow, particularly of rivers and canals. Conversions: 1 ft3/s = = = = Cubic foot per minute The IEEE symbol for the cubic foot per minute is ft3/min. The following abbreviations are used: • cu ft/min • • cfm or CFM • cfpm or CFPM Cubic feet per minute is used to measure the amount of air that is being delivered, and is a common metric used for carburetors, pneumatic tools, and air-compressor systems. == Standard cubic foot ==

A standard cubic foot (abbreviated scf) is a measure of quantity of gas, sometimes defined in terms of standard temperature and pressure as a cubic foot of volume at and of pressure. == See also ==
