The cubic foot (symbol ft3 or cu ft)[1] is an imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot (0.3048 m) in length, or exactly 28.316846592 L (which differs by about 1% from Page Template:Sfrac/styles.css has no content.1/35 of a cubic metre, making that a suitable approximation in many cases).

Symbols and abbreviations
The IEEE symbol for the cubic foot is ft3.[1]Template:R/superscript The following abbreviations are used: cubic feet, cubic foot, cubic ft, cu feet, cu foot, cu ft, cu.ft, cuft, cb ft, cb.ft, cbft, cbf, feet3, foot3, ft3, feet/-3, foot/-3, ft/-3.[citation needed]
Larger multiples are in common usage in commerce and industry in the United States:
- CCF or HCF: Centum (Latin hundred) cubic feet; i.e., Template:Cvt
- Used in the billing of natural gas and water supply delivered to households.
- MCF: Mille (Latin thousand) cubic feet; i.e., Template:Cvt
- MMCF: Mille mille (= million) cubic feet; i.e., Template:Cvt
- MMCFD: MMCF per day; i.e., Template:Cvt
- Used in the oil and gas industry.
- BCF or TMC: Billion or thousand million cubic feet; i.e., Template:Cvt
- TMC is usually used for referring to storage capacity and actual storage volume of storage dams.
- TCF: Trillion cubic feet; i.e., Template:Cvt
- 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.[1]Template:R/superscript 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,[2] used mostly in the United States in the context of water flow, particularly of rivers and canals.
Conversions: 1 ft3/s = Template:Cvt = Template:Cvt = Template:Cvt = Template:Cvt
Cubic foot per minute
The IEEE symbol for the cubic foot per minute is ft3/min.[1]Template:R/superscript The following abbreviations are used:
- cu ft/min
- cufm
- 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,[3] pneumatic tools, and air-compressor systems.[4]
Standard cubic foot
Script error: No such module "Labelled list hatnote". Script error: No such module "Labelled list hatnote". A standard cubic foot (abbreviated scf) is a measure of quantity of gas, sometimes[<span title="Script error: No such module "decodeEncode".">clarification needed] defined in terms of standard temperature and pressure as a cubic foot of volume at 60 °F (16 °C; 289 K) and 14.7 pounds per square inch (1.01 bar; 101 kPa) of pressure.[citation needed]
