How to convert kilometers to nanometers
One kilometer is equal to 999,999,999,999.99987793 nanometers. To convert kilometers to nanometers, multiply the kilometer value by 999,999,999,999.99987793.
nm = km × 999,999,999,999.99987793
Example
Convert 5 kilometers to nanometers:
nm = 5 × 999,999,999,999.99987793 = 5,000,000,000,000 nm
