The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space ..more definition+
The x unit (symbol xu) is a unit of length approximately equal to 0.1 pm (10−13 m). It is used to quote the wavelength of X-rays and gamma rays.
In relation to the base unit of [length] => (meters), 1 Light Seconds (ls) is equal to 299800000 meters, while 1 X Unit (xu) = 1.002004E-13 meters.| 256500 Light Seconds | to common length units |
