How to Convert Megaparsec to X-Unit
1 Mpc = 3.07927269407632e+35 X
Example: convert 15 Mpc to X:
15 Mpc = 15 × 3.07927269407632e+35 X = 4.61890904111448e+36 X
Megaparsec to X-Unit Conversion Table
| megaparsec | X-unit |

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.
X-Unit
An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.
History/Origin
The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.
Current Use
The X-unit has been largely replaced by the angstrom and the picometer.
