Symbols and abbreviations
The IEEE symbol for the cubic foot is ft3.[1] 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., 100 ft3
- Used in the billing of natural gasand water delivered to households.
- Used in the
- MCF: Mille (Latin thousand) cubic feet; i.e., 1000 ft3
- MMCF: Mille mille cubic feet; i.e., 1000000 ft3
- MMCFD: MMCF per day; i.e., 1000000 ft3/d
- Used in the oil and gas industry.
- Used in the
- BCF or TMC: Billion or thousand million cubic feet; i.e., 1000000000 ft3
- TMC is usually used for referring to storage capacity and actual storage volume of storage dams.
- TCF: Trillion cubic feet; i.e., 1000000000000 ft3
- Used in the oil and gas industry.
The IEEE symbol for the cubic foot per second is ft3/s.[1] 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 ft3s−1 = 0.0283168 m3/s = 28.3168 L/s = 1.699011 m3/min = 1,699.011 L/min
Cubic foot per minute
The IEEE symbol for the cubic foot per minute is ft3/min.[1] 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 carburettors,[3] pneumatic tools, and air-compressor systems.[4]
