Foot (Us Survey)
The U.S. survey foot was a unit of length defined as exactly 1200/3937 meters.
History/Origin
The U.S. survey foot was used for land surveying in the United States for most of the 20th century. Its use was officially phased out in 2022 to standardize with the international foot.
Current Use
The U.S. survey foot is now an obsolete unit.
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.
