Convert chain to Earth's equatorial radius
Please provide values below to convert chain [ch] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to chain.
1 ch = 3.15402444319e-06 R_e. To convert chain to Earth's equatorial radius, multiply the value by 3.15402444319e-06; to go the other way, divide by it (1 R_e = 317055.247355 ch). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Chain
A chain is a unit of length equal to 66 feet, or 22 yards.
History/Origin
The chain was developed by English surveyor Edmund Gunter in the early 17th century. It was designed to be a convenient length for surveying land.
Current Use
The chain is still used in some surveying applications and is the length of a cricket pitch.
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.
