Convert a.u. of length to light year
Please provide values below to convert a.u. of length [a.u., b] to light year [ly], or Convert light year to a.u. of length.
1 a.u., b = 5.5934e-27 ly. To convert a.u. of length 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., b). 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., b = 5.5934e-27 ly
- 1 ly = 1.7878e+26 a.u., b
- 10 a.u., b = 5.5934e-26 ly
- 100 a.u., b = 5.5934e-25 ly
How to Convert A.u. Of Length to Light Year
1 a.u., b = 5.59340793539899e-27 ly
Example: convert 15 a.u., b to ly:
15 a.u., b = 15 × 5.59340793539899e-27 ly = 8.39011190309848e-26 ly

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.
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
