Convert **x unit** to **light year**

Selected category: length.

X unit (Xu) is a unit of length used for measuring the wavelength of x-rays and gamma rays. This unit is approximately 1.0021 x 10^{-13} meter.

Light year (ly) is a unit of distance used by astronomers. One light year is defined from the International Astronomical Union as the distance that light travels in one Julian year (365.25 days) through a vacuum. The defined light speed is c = 299,792,458 m/sec. So one light year equals exactly 9 460 730 472 580 800 meters.

Swap, do a light year to x unit conversion.
