Please provide values below to convert a.u. of length [a.u., b] to megaparsec [Mpc], or Convert megaparsec to a.u. of length.
How to Convert A.u. Of Length to Megaparsec
1 a.u., b = 1.71494666912182e-33 Mpc
Example: convert 15 a.u., b to Mpc:
15 a.u., b = 15 × 1.71494666912182e-33 Mpc = 2.57242000368273e-32 Mpc

A.u. Of Length
The atomic unit of length, also known as the Bohr radius (a₀), is approximately 5.29 x 10⁻¹¹ meters.
History/Origin
The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.
Current Use
The atomic unit of length is used in atomic physics to simplify calculations and equations.
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.
