Fermi
A fermi is a unit of length equal to a femtometer, which is 10⁻¹⁵ meters.
History/Origin
The fermi is named after the Italian-American physicist Enrico Fermi. It was a popular unit in nuclear physics.
Current Use
The femtometer is the officially recognized SI unit, but the fermi is still used informally in nuclear and particle physics.
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.
