Micrometers (μm)
Definition
A micrometer (μm), also called a micron, is a metric unit of length equal to one millionth of a meter (10⁻⁶ m).
History
The micrometer gained prominence in the 19th century with the development of precision optics and microscopy. The term 'micron' was officially revoked by the SI in 1967, though it remains in common use.
Current use
Micrometers are used in biology (cell sizes: 1–100 μm), materials science (thin film thickness), manufacturing (surface roughness), and air quality measurement (PM2.5 refers to particles ≤2.5 μm).
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).
