Convert ell to Earth's equatorial radius
Please provide values below to convert ell [ell] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to ell.
1 ell = 1.79205934272e-07 R_e. To convert ell to Earth's equatorial radius, multiply the value by 1.79205934272e-07; to go the other way, divide by it (1 R_e = 5580172.35346 ell). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Ell
The ell is an obsolete unit of length, originally used for measuring cloth. Its length varied in different countries, but it was generally around 45 inches.
History/Origin
The word "ell" is derived from the Latin "ulna," meaning "forearm," as the unit was originally based on the length of the forearm.
Current Use
The ell is no longer in use.
Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
