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.
Nanometer (nm)
Definition: A nanometer (symbol: nm) is one-billionth of a meter (0.000000001 m). It operates at the atomic and molecular scale, pivotal for nanotechnology and quantum physics.
History: Became relevant in the late 20th century with advances in electron microscopy and the rise of nanotechnology. The 1983 meter definition enabled its precise standardization.
Current use: Fundamental in chip fabrication (CPU node sizes, e.g., 7nm), DNA research (helix width ≈ 2nm), and optics (visible light wavelengths range 380–700nm).
