Convert Earth's polar radius to megaparsec
Please provide values below to convert Earth's polar radius [R_p] to megaparsec [Mpc], or Convert megaparsec to Earth's polar radius.
How to Convert Earth's Polar Radius to Megaparsec
1 R_p = 2.0600831203379e-16 Mpc
Example: convert 15 R_p to Mpc:
15 R_p = 15 × 2.0600831203379e-16 Mpc = 3.09012468050685e-15 Mpc

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.
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.
