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.
Fathom
A fathom is a unit of length equal to 6 feet, used especially for measuring the depth of water.
History/Origin
The term "fathom" comes from the Old English word "fæthm," meaning "outstretched arms," as the distance was originally the span of a man's outstretched arms.
Current Use
The fathom is still used in nautical applications, especially in the United States, to measure water depth. It is also used in commercial fishing to measure the length of lines.
