About Kilometer (km)
Equal to 1,000 meters, the kilometer is the standard unit for measuring road distances, marathon courses (42.195 km), and geographic separations in most countries. Road signs across Europe, Asia, and South America display distances in kilometers, making it one of the most universally encountered metric units.
About Light-year (ly)
The distance light travels in one Julian year -- approximately 9.461 trillion kilometers -- the light-year is the standard unit for expressing interstellar distances. Proxima Centauri, the nearest star beyond the Sun, lies about 4.24 light-years away. Despite its name, the light-year measures distance, not time.
