Cubic foot
The cubic foot (symbol ft3)[1] is an imperial and US customary (non-metric) unit of volume, used in the United States, and partially in Canada, and the United Kingdom. It is defined as the volume of a cube with sides of one foot (0.3048 m) in length. Its volume is 28.3168 liters or about 1⁄35 of a cubic meter.
At 60 °F (16 °C), a cubic foot of water weighs 62.36630 pounds (28.28888 kg).

Cubic feet per minute is used to measure the amount of air that's being delivered and is a common metric used for carburetors, [5] pneumatic tools, and air compressor systems.[6]
Standard cubic foot
A standard cubic foot (abbreviated scf) is a measure of quantity of gas, sometimes[clarification needed] defined in terms of standard temperature and pressure as a cubic foot of volume at 60 degrees Fahrenheit (15.56 °C; 288.71 K) and 14.7 pounds per square inch (PSI) (1.01 bar; 101.35 kPa) of pressure.[citation needed]
