Nanometers (nm)
Definition
A nanometer (nm) is a metric unit of length equal to one billionth of a meter (10⁻⁹ m). It is part of the International System of Units (SI).
History
The nanometer became important in the 20th century with advances in microscopy and semiconductor technology. The prefix 'nano' comes from the Greek word 'nanos' meaning dwarf.
Current use
Nanometers are essential in nanotechnology, semiconductor manufacturing (chip node sizes like 5 nm, 3 nm), molecular biology (DNA strand width ~2.5 nm), and light wavelength measurement (visible light: 380–700 nm).
Kilometers (km)
Definition
A kilometer (km) is a metric unit of length equal to 1,000 meters. It is the standard unit for expressing long distances in the metric system.
History
The kilometer was adopted as part of the metric system in 1795. It became the standard long-distance unit across most of the world, though the United States, United Kingdom, and a few other countries still primarily use miles.
Current use
Kilometers are used worldwide for road distances, geographic measurements, running and cycling events, vehicle odometers (in metric countries), and aviation altitude in some regions.
