Convert ell to meter
Ell
An ell is a historical unit of length that varied considerably across countries and eras, most commonly associated with cloth measurement. The English ell was standardised at 45 inches (1.143 metres), while the Flemish ell measured approximately 27 inches and the Scottish ell about 37 inches. Derived from the Latin ulna (forearm), the ell was widely used by textile merchants and tailors throughout medieval and early modern Europe.
Meter
The metre (Commonwealth spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μετρούν, "measure") is the base unit of length in the International System of Units (SI). The SI unit symbol is m. The metre is defined as the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately 40000 km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. In 1983, the current definition was adopted.
