Convert light year to a.u. of length
Please provide values below to convert light year [ly] to a.u. of length [a.u., b], or Convert a.u. of length to light year.
1 ly = 1.7878e+26 a.u., b. To convert light year to a.u. of length, multiply the value by 1.7878e+26; to go the other way, divide by it (1 a.u., b = 5.5934e-27 ly). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 ly = 1.7878e+26 a.u., b
- 1 a.u., b = 5.5934e-27 ly
- 10 ly = 1.7878e+27 a.u., b

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.
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.
