About nanometers and kilometers
Nanometer (nm)
A nanometer (nm) is one billionth of a meter. It is used for wavelengths of light and for sizes at the atomic and molecular scale.
Kilometer (km)
A kilometer (km) is 1,000 meters. It is the standard unit for road distances in India and most of the world.
nm to km: common questions
