Convert light year to X-unit
Please provide values below to convert light year [ly] to X-unit [X], or Convert X-unit to light year.
1 ly = 9.4411e+28 X. To convert light year to X-unit, multiply the value by 9.4411e+28; to go the other way, divide by it (1 X = 1.0592e-29 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 = 9.4411e+28 X
- 1 X = 1.0592e-29 ly
- 10 ly = 9.4411e+29 X
- 100 ly = 9.4411e+30 X
How to Convert Light Year to X-Unit
1 ly = 9.44109299914178e+28 X

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.
X-Unit
An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.
History/Origin
The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.
Current Use
The X-unit has been largely replaced by the angstrom and the picometer.
