About these units
Micrometer (µm)
- Definition
- A micrometer or micron (µm) is one millionth of a meter, used to measure microscopic objects.
- History
- The term "micron" was officially adopted in 1879 and renamed micrometer by the SI in 1967.
- Current use
- Micrometers describe cell sizes, bacteria, fibres, and semiconductor and optical manufacturing tolerances.
Kilometer (km)
- Definition
- A kilometer (km) is 1,000 meters and is the metric unit used for measuring longer distances such as roads and travel.
- History
- It entered use with the metric system in the 1790s, combining the SI prefix "kilo-" (thousand) with the meter.
- Current use
- Most of the world expresses road distances and speed limits in kilometers; the main exceptions are the United States and the United Kingdom, which still use miles.
