How the conversion works
Multiply by 1.000000000e-12 to go from nanometer 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 nanometer — 1 km = 1,000,000,000,000 nm.
