Convert Bohr radius to light year
Please provide values below to convert Bohr radius [a.u.] to light year [ly], or Convert light year to Bohr radius.
1 a.u. = 5.5934e-27 ly. To convert Bohr radius to light year, multiply the value by 5.5934e-27; to go the other way, divide by it (1 ly = 1.7878e+26 a.u.). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 a.u. = 5.5934e-27 ly
- 1 ly = 1.7878e+26 a.u.
- 10 a.u. = 5.5934e-26 ly
- 100 a.u. = 5.5934e-25 ly
How to Convert Bohr Radius to Light Year
1 a.u. = 5.59340753271338e-27 ly
Example: convert 15 a.u. to ly:
15 a.u. = 15 × 5.59340753271338e-27 ly = 8.39011129907007e-26 ly

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.
Light Year
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
Frequently Asked Questions
What is 1 Bohr radius in light year?
1 Bohr radius (a.u.) = 5.5934e-27 light year (ly).
