Ell
The ell is an obsolete unit of length, originally used for measuring cloth. Its length varied in different countries, but it was generally around 45 inches.
History/Origin
The word "ell" is derived from the Latin "ulna," meaning "forearm," as the unit was originally based on the length of the forearm.
Current Use
The ell is no longer in use.
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.
