History

Kilometer (km)

The kilometer, or km, is a unit in the metric system that equals 1,000 meters. It was established as part of the metric system during the French Revolution and soon became the default for measuring longer distances. The word “kilometer” is derived from the Greek for “thousand” (chilioi) and “measure” (metron). Kilometers are widely adopted for measuring travel distances, geographic features, maps, and sporting events in most countries. In contrast, the mile is still used in countries like the United States and the UK. The kilometer’s decimal structure makes calculations simple and has been essential to transportation planning, GPS technologies, and international measurement standards.

Nanometer (nm)

The nanometer, symbolized as nm, equals one billionth of a meter and is vital in nanotechnology, physics, and chemistry. It was first defined with the development of atomic-scale research in the 20th century. Nanometers are used to measure light wavelengths, semiconductor features, and molecules, playing a crucial role in electronics, optics, and biotechnology. The unit exemplifies the precision and scalability of the metric system, enabling scientists and engineers to explore dimensions at the atomic and molecular levels. Its adoption has revolutionized modern technology and scientific understanding.
