How the conversion works

Multiply by 100,000 to go from kilometer to centimeter, or divide by it to go back. Every conversion on this site routes through the SI value (m) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.

Going the other way? centimeter to kilometer — 1 cm = 0.00001 km.
