Convert megaparsec to Earth's polar radius
Please provide values below to convert megaparsec [Mpc] to Earth's polar radius [R_p], or Convert Earth's polar radius to megaparsec.
How to Convert Megaparsec to Earth's Polar Radius
1 Mpc = 4.85417306771573e+15 R_p
Example: convert 15 Mpc to R_p:
15 Mpc = 15 × 4.85417306771573e+15 R_p = 7.28125960157359e+16 R_p
Megaparsec to Earth's Polar Radius Conversion Table

Megaparsec
A megaparsec is a unit of distance used in astronomy, equal to one million parsecs.
History/Origin
The parsec was first coined by British astronomer Herbert Hall Turner in 1913. The megaparsec came into use as astronomical distance measurements extended to other galaxies.
Current Use
The megaparsec is used to measure the distances between neighboring galaxies and galaxy clusters.
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.
