How to convert megaparsecs to light years
1 megaparsec is equal to 3,261,563.777 light years, and 1 light year is equal to 3.066013938 × 10⁻⁷ megaparsecs. To convert, multiply by the conversion factor:
light years = megaparsecs × 3,261,563.777
light years = megaparsecs ÷ 3.066013938 × 10⁻⁷Example: convert 1 Mpc to ly: 1 × 3,261,563.777 = 3,261,563.777 ly.

About the megaparsec
A megaparsec is one million parsecs (about 3.26 million light-years). It's used for distances between galaxies and in the Hubble constant (km/s/Mpc).

About the light year
A light-year is the distance light travels in a vacuum in one Julian year (365.25 days): about 9.46 trillion km. The nearest star system, Alpha Centauri, is about 4.37 light-years away.
