Fermi


A fermi is a unit of length used in nuclear physics to measure extremely small distances, such as the size of atomic nuclei. It is equal to 1 femtometer (fm), which is 10⁻¹⁵ meters.


The unit is named after the Italian physicist Enrico Fermi, known for his work in nuclear physics.


Key facts:



  • 1 fermi = 1 femtometer = 10⁻¹⁵ meters



  • Used to measure nuclear dimensions and particle sizes



  • Essential in the study of nuclear and particle physics



The fermi is vital for describing distances at the subatomic scale, much smaller than atoms and molecules.


Fathom


A fathom is a unit of length traditionally used to measure the depth of water. It equals 6 feet or approximately 1.8288 meters.


Originating from the Old English word fæðm, meaning "to embrace" or "outstretched arms," the fathom was based on the average distance between a person's outstretched arms. It has been widely used by sailors and navigators to estimate sea depths and underwater distances.


Key facts:



  • 1 fathom = 6 feet



  • 1 fathom ≈ 1.8288 meters



  • 1 fathom = 2 yards



Though modern sonar and electronic instruments now measure depth more precisely, the fathom remains a traditional unit in nautical contexts, especially in maritime charts and historical references.
