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.
Kilometer
A kilometer is a unit of length in the metric system, equal to one thousand meters.
History/Origin
The term "kilometer" is derived from the Greek words "khilioi" (thousand) and "metron" (measure). The kilometer was first defined as part of the metric system in France in 1795.
Current Use
The kilometer is the most widely used unit of distance for road signs and travel distances in the world, with the notable exceptions of the United States and the United Kingdom.
