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.
League
A league is a unit of length that was common in Europe and Latin America, but is no longer an official unit in any nation. It was the distance a person could walk in an hour.
History/Origin
The league varied in length from country to country and even within the same country over time. The most common definition was three miles.
Current Use
The league is no longer in common use but is found in historical texts and literature.
