About these units

Nanometer (nm)

Definition
A nanometer (nm) is one billionth of a meter, the scale of atoms, molecules, and wavelengths of light.
History
It combines the SI prefix "nano-" (one billionth) with the meter and became common with the rise of nanotechnology.
Current use
Nanometers measure the wavelengths of visible light (about 380–750 nm) and the feature sizes of modern microchips.

Kilometer (km)

Definition
A kilometer (km) is 1,000 meters and is the metric unit used for measuring longer distances such as roads and travel.
History
It entered use with the metric system in the 1790s, combining the SI prefix "kilo-" (thousand) with the meter.
Current use
Most of the world expresses road distances and speed limits in kilometers; the main exceptions are the United States and the United Kingdom, which still use miles.
