How to convert Kilometers to Light Years
Multiply the kilometers value by 1.057e-13: 1 km = 1.057e-13 ly. Going the other way, 1 ly = 9.461e+12 km, so divide by 1.057e-13 or use the Light Years to Kilometers converter.
About these units
Kilometers (km)
A kilometer is 1,000 meters, the standard unit for road distances and travel in most of the world. One kilometer is about 0.621 miles.
Light Years (ly)
A light-year is the distance light travels through a vacuum in one Julian year, about 9.461 trillion kilometers. Despite the name it measures distance, not time, and is used for stars and galaxies.
