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.

The zhang (Chinese: 丈) is a customary Chinese unit of length equal to 10 chi (Chinese feet). [1][2] Its value varied over time and place with different values of the chi, although it was occasionally standardized. In 1915, the Republic of China set it equal to about 3.2 meters or 3.50 yards. In 1930, this was revised to an exact value of 3⅓ ...
One barn is equal to 1.0 × 10 −28 m 2. The name derives from the folk expressions "As big as a barn," and "Couldn't hit the broad side of a barn", used by particle accelerator physicists to refer to the probability of achieving a collision between particles. For nuclear purposes, 1.0 × 10 −28 m 2 is actually rather large. [25]

Forensic estimation of stature is part of the identification process necessary when dismembered body parts are found. It is also possible to estimate the stature from bones. [2] Even measurements of parts of the body, such as a finger, can be used to estimate the stature. [3][4] The principle behind this forensic anthropology technique is the ...
Symbol. M☉. In SI base units. 1.988 416 × 1030 kg[1] The solar mass (M☉) is a standard unit of mass in astronomy, equal to approximately 2 × 1030 kg. It is approximately equal to the mass of the Sun. It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes.
[7] [8] The portals of each tube contain flood doors weighing 20 short tons (18 long tons; 18 t) and measuring 2 feet (0.61 m) thick, 14 feet (4.3 m) across, and 29 feet (8.8 m) tall. [9] The tunnel was originally commissioned by the New York City Tunnel Authority, whose chief engineer Ole Singstad created the tunnel's original designs.
