Please provide values below to convert a.u. of length [a.u., b] to kiloparsec [kpc], or Convert kiloparsec to a.u. of length.
How to Convert A.u. Of Length to Kiloparsec
1 a.u., b = 1.71494666912182e-30 kpc
Example: convert 15 a.u., b to kpc:
15 a.u., b = 15 × 1.71494666912182e-30 kpc = 2.57242000368272e-29 kpc

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.
Kiloparsec
A kiloparsec is a unit of distance used in astronomy, equal to one thousand parsecs.
History/Origin
The parsec was first proposed as a unit of distance in 1913 by British astronomer Herbert Hall Turner. The kiloparsec is a multiple of the parsec used for larger astronomical distances.
Current Use
The kiloparsec is used to measure distances to objects within and around the Milky Way galaxy.
