Chain (Us Survey)
A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.
History/Origin
The U.S. survey chain 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
The U.S. survey chain was used for land surveying in the United States.
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.
