Convert parsec to Bohr radius
Please provide values below to convert parsec [pc] to Bohr radius [a.u.], or Convert Bohr radius to parsec.
1 pc = 5.8311e+26 a.u.. To convert parsec to Bohr radius, multiply the value by 5.8311e+26; to go the other way, divide by it (1 a.u. = 1.7149e-27 pc). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 pc = 5.8311e+26 a.u.
- 1 a.u. = 1.7149e-27 pc
- 10 pc = 5.8311e+27 a.u.
- 100 pc = 5.8311e+28 a.u.
How to Convert Parsec to Bohr Radius
1 pc = 5.83108553751687e+26 a.u.
Example: convert 15 pc to a.u.:
15 pc = 15 × 5.83108553751687e+26 a.u. = 8.74662830627531e+27 a.u.

Parsec
A parsec is a unit of length used to measure the large distances to astronomical objects outside the Solar System, approximately equal to 3.26 light-years. It is the distance at which one astronomical unit subtends an angle of one arcsecond.
History/Origin
The term "parsec" is a portmanteau of "parallax" and "second," coined by British astronomer Herbert Hall Turner in 1913.
Current Use
The parsec is the preferred unit of distance in astronomy and astrophysics for expressing the distances to stars and galaxies.
Bohr Radius
The Bohr radius is the most probable distance between the proton and the electron in a hydrogen atom in its ground state, 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. It is the atomic unit of length.
Current Use
The Bohr radius is a fundamental constant in atomic physics and is used to simplify calculations and equations.
