  1. 1 km = 1000000000000 nm
  2. 1 × 1000000000000 = 1000000000000 nm

How to convert kilometers to nanometers

1 km = 1000000000000 nm, so multiply by 1000000000000 to go from kilometers to nanometers. Going the other way, 1 nm = 1 × 10^-12 km.

nm = km × 1000000000000
km = nm × 1

Worked example:

1 km = 1000000000000 nm
5 × 1000000000000 = 5000000000000 nm
