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

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.
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.
