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