Convert centiinch to Earth's polar radius
Enter a value below to convert centiinch [cin] to Earth's polar radius [R_p]. Reverse conversion: Convert Earth's polar radius to centiinch.
1 cin = 3.9958e-11 R_p. To convert centiinch to Earth's polar radius, multiply the value by 3.9958e-11; to go the other way, divide by it (1 R_p = 25026583858.3 cin). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Centiinch: Definition and Use
A centiinch is a unit of length equal to one-hundredth of an inch.
History/Origin
The centiinch is not a standard unit of measurement but is a logical subdivision of the inch.
Current Use
The centiinch is rarely used.
Earth's Polar Radius: Definition and Use
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.
