Convert Earth's polar radius to chain
Please provide values below to convert Earth's polar radius [R_p] to chain [ch], or Convert chain to Earth's polar radius.
1 R_p = 315992.220433 ch. To convert Earth's polar radius to chain, multiply the value by 315992.220433; to go the other way, divide by it (1 ch = 3.1646348718e-06 R_p). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
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.
