About Megaparsec (Mpc)
The megaparsec is equal to one million parsecs, approximately 3.26 million light-years, used for measuring distances between galaxies and in cosmology.
1 Mpc = 10⁶ pc = 3.0857 × 10²² m ≈ 3.262 × 10⁶ light-years.
To convert Mpc to light-years: multiply by 3.262 × 10⁶. To convert Mpc to meters: multiply by 3.0857 × 10²².
Measuring distances to galaxy clusters, Hubble flow calculations, and large-scale structure mapping.
The Andromeda Galaxy is about 0.78 Mpc away. The Virgo Cluster is about 16.5 Mpc distant.
Confusing Mpc with kpc — they differ by a factor of 1,000. kpc = within galaxies, Mpc = between galaxies.
Hubble's constant links distance (Mpc) to recession speed (km/s): the farther away a galaxy is, the faster it recedes.
