From these figures for the size of a Biblical ell, that of the basic unit — the finger-breadth ( Etzba) — can be calculated to be either 2.1 or 2.2 cm (0.83 or 0.87 in); Rav Avraham Chaim Naeh approximates at 2 cm (0.79 in); Talmudic scholar Chazon Ish at 2.38 cm (0.94 in). The mile ( Mil) is thus about 963 or 1146 meters (3160 or 3760 ft ...

Length. For measuring length, the U.S. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. From 1893, the foot was legally defined as exactly 1200⁄3937 m (approximately 0.304 8006 m ). [13] Since July 1, 1959, the units of length have been defined on the basis of 1 yd ...
A light-year, alternatively spelled light year ( ly or lyrr [3] ), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km ( Scientific notation: 9.4607304725808 × 10 12 km), which is approximately 5.88 trillion mi.
Imperial/U.S. The basic unit of length in the imperial and U.S. customary systems is the yard, defined as exactly 0.9144 m by international treaty in 1959. [2] [5] Common imperial units and U.S. customary units of length include: [6] thou or mil ( 1⁄1000 of an inch) inch ( 25.4 mm) foot (12 inches, 0.3048 m) yard (3 feet, 0.9144 m)
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
