A U.S. survey rod is a unit of length equal to 16.5 U.S. survey feet.
History/Origin
The U.S. survey rod is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.
Current Use

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.
