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).
Feet (ft)
Definition
A foot (ft) is an imperial unit of length equal to 12 inches or exactly 0.3048 meters.
History
The foot has been used since antiquity - ancient civilizations based it on the length of a human foot. The modern international foot was standardized in 1959 to exactly 0.3048 meters by agreement between English-speaking nations.
Current use
Feet are the standard unit for measuring human height, room dimensions, building elevation, and altitude in aviation in the United States, United Kingdom, Canada, and several other countries.
