The cubic foot (symbol ft 3 or cu ft) [1] 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 L (about 1 ⁄ 35 of a cubic metre).
In ancient Rome, according to Vitruvius, a cubit was equal to 1 + 1 ⁄ 2 Roman feet or 6 palm widths (approximately 444 mm or 17 + 1 ⁄ 2 in). [23] A 120-centimetre cubit (approximately four feet long), called the Roman ulna, was common in the Roman empire, which cubit was measured from the fingers of the outstretched arm opposite the man's hip.
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
A board foot is a United States and Canadian unit of approximate volume, used for lumber. It is equivalent to 1 inch × 1 foot × 1 foot (144 cu in or 2,360 cm 3). It is also found in the unit of density pounds per board foot. In Australia and New Zealand the terms super foot or superficial foot were formerly used for this unit. The exact ...
One cubit was equal to 0.464 m (18.5 in). [2] The Bam̆ba (Fathom), still in use as of 2016, is the distance between a man's outstretched arms. It is roughly 6 feet in length. "Bam̆ba" is usually used to measure depth in wells and pits. [1]

Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
