How the conversion works
Multiply by 0.00001 to go from centimeter to kilometer, 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? kilometer to centimeter: 1 km = 100,000 cm.
