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).
Hectometers (hm)
Definition
A hectometer (hm) is a metric unit of length equal to 100 meters.
History
The hectometer is part of the metric prefix system. While rarely used as a standalone unit, it is inherent in the hectare (1 ha = 1 hm²), one of the most widely used land measurement units.
Current use
Hectometers are seldom used directly but are implicit in hectare measurements for agriculture and land management. They occasionally appear in distance markers along European roadways.
