Cubic foot
The cubic foot (symbol ft^{3})^{[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).
