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).
Inches (in)
Definition
An inch (in) is an imperial unit of length equal to 1/12 of a foot or exactly 25.4 millimeters.
History
The inch has ancient origins, historically defined as the width of a man's thumb. It was standardized internationally in 1959 to exactly 25.4 mm. The word 'inch' derives from the Latin 'uncia' meaning one-twelfth.
Current use
Inches are widely used in the United States, Canada, and the United Kingdom for everyday measurements: screen sizes, paper dimensions, height measurements, pipe diameters, and construction specifications.
