Convert megameter to Earth's polar radius
Please provide values below to convert megameter [Mm] to Earth's polar radius [R_p], or Convert Earth's polar radius to megameter.
1 Mm = 0.157313035463 R_p. To convert megameter to Earth's polar radius, multiply the value by 0.157313035463; to go the other way, divide by it (1 R_p = 6.3567523 Mm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Mm = 0.157313035463 R_p
- 1 R_p = 6.3567523 Mm
- 10 Mm = 1.57313035463 R_p

Megameter
A megameter is a unit of length in the metric system equal to 10^6 meters.
History/Origin
The prefix "mega-" for 10^6 was adopted by the CGPM (General Conference on Weights and Measures) in 1873.
Current Use
The megameter is sometimes used to specify the diameters of planets and the distances of satellites.
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.
