Micrometer
A micrometer, also known as a micron, 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 "micrometer" became the official term.
Current Use
The micrometer is a common unit for measuring the wavelength of infrared radiation, as well as the size of biological cells and bacteria. It is also widely used in technology and engineering.
X-Unit
An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.
History/Origin
The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.
Current Use
The X-unit has been largely replaced by the angstrom and the picometer.
