Micron
A micron is a non-SI name for micrometer (µm), which is a unit of length equal to one-millionth of a meter.
History/Origin
The term "micron" and the symbol µ were officially declared obsolete by the General Conference on Weights and Measures (CGPM) in 1967 and are now discouraged.
Current Use
While the term micrometer is the officially recognized term, "micron" is still used in some industries and in casual speech.
Femtometer
A femtometer is a unit of length in the metric system equal to 10^-15 meters. It is also known as a fermi.
History/Origin
The prefix "femto-" for 10^-15 was adopted by the CGPM (General Conference on Weights and Measures) in 1964. The unit is also named after the physicist Enrico Fermi.
Current Use
The femtometer is primarily used in nuclear physics to measure the size of atomic nuclei.
