How to Convert Kiloparsec to Earth's Polar Radius
1 kpc = 4854173067715.73 R_p
Example: convert 15 kpc to R_p:
15 kpc = 15 × 4854173067715.73 R_p = 72812596015735.9 R_p
Kiloparsec to Earth's Polar Radius Conversion Table
| kiloparsec | Earth's polar radius |

Kiloparsec
A kiloparsec is a unit of distance used in astronomy, equal to one thousand parsecs.
History/Origin
The parsec was first proposed as a unit of distance in 1913 by British astronomer Herbert Hall Turner. The kiloparsec is a multiple of the parsec used for larger astronomical distances.
Current Use
The kiloparsec is used to measure distances to objects within and around the Milky Way galaxy.
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.
