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.
Light Year (ly)
- Definition
- A light-year (ly) is the distance light travels in one year in a vacuum, about 9.46 trillion kilometers.
- History
- The concept arose in the 19th century as astronomers sought an intuitive way to express the vast distances between stars.
- Current use
- Light-years express distances to stars and galaxies in astronomy and popular science.
