Cubic foot
Template:Short description Template:Infobox unit 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 (Script error: No such module "val".) in length, or exactly Script error: No such module "convert"., which is very close to Template:Sfrac of a cubic metre).

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.
The IEEE symbol for the cubic foot per second is ft3/s.Template:R 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.Template:R The following abbreviations are used:
- cu ft/min
- Template:Notatypo
- 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]
