How to convert megaparsecs to atomic units of length
1 megaparsec is equal to 5.831085538 × 10³² atomic units of length, and 1 a.u. of length is equal to 1.714946546 × 10⁻³³ megaparsecs. To convert, multiply by the conversion factor:
atomic units of length = megaparsecs × 5.831085538 × 10³²
atomic units of length = megaparsecs ÷ 1.714946546 × 10⁻³³Example: convert 1 Mpc to a₀: 1 × 5.831085538 × 10³² = 5.831085538 × 10³² a₀.

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).
