Kilometer (km)
Definition: A kilometer (symbol: km) is a unit of length in the International System of Units (SI). One kilometer equals 1,000 meters or approximately 0.6214 miles.
History: The prefix 'kilo-' denotes a thousand. The kilometer's origin is tied to the meter, evolving alongside its definitions. Its modern interpretation relies on the 1983 definition of the meter based on the speed of light, ensuring global consistency.
Current use: It is the standard unit for expressing geographical distances (e.g., between cities) in most countries. The US and UK still use miles for road distances, though the UK officially adopted the metric system for other applications.
Micrometer (µm)
Definition: A micrometer (symbol: µm), or micron, is one-millionth of a meter (0.000001 m). It measures microscopic structures like cells and wavelengths of infrared light.
History: Gained prominence with the development of microscopy in the 17th century. The term 'micron' was officially deprecated in 1967 in favor of 'micrometer' to align with SI standards.
Current use: Critical in biology (cell diameters), semiconductor manufacturing (transistor features), and air quality monitoring (particulate matter like PM2.5).
