# Cubic foot

The **cubic foot** 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. Its volume is 28.3168 litres or about ^{1}⁄_{35} of a cubic metre.

A cubic foot of water weighs 62 pounds (28 kg).

## Standard cubic foot

A standard cubic foot (abbreviated **scf**) is a measure of quantity of gas, sometimes but not always^{[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]}
