The cubic foot (symbol ft3 or cu ft) 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, or exactly 28.316846592 L (which is about 1% off of 1/35 of a cubic metre, making that a suitable approximation in many cases).
