Convert Earth's equatorial radius to megaparsec
Please provide values below to convert Earth's equatorial radius [R_e] to megaparsec [Mpc], or Convert megaparsec to Earth's equatorial radius.
How to Convert Earth's Equatorial Radius to Megaparsec
1 R_e = 2.06701342962547e-16 Mpc
Example: convert 15 R_e to Mpc:
15 R_e = 15 × 2.06701342962547e-16 Mpc = 3.10052014443821e-15 Mpc

Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
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.
