## Unit Information

Fermi
/ˈfəːmi/
Symbol: fm
Unit System: Non-SI metric

### What is the Fermi?

The fermis is a unit of length in the non-SI metric system and uses the symbol fm.

One fermi is equal to 1×10−15m or 3.9370×10−14 in.

It is used to measure nuclear distances and was named after the Italian physicist Enrico Fermi (1901–1954). It has now been replaced with the SI-derived term femtometre.

Fathom
/ˈfað(ə)m/
Symbol: ftm
Unit System: Imperial

### What is the Fathom?

The fathom is a unit of length in the imperial unit system and uses the symbol ftm.

One fathom is equal to 6 feet or 1.8288m.

The phrase fathom derives from an old English derivative of a Viking / Danish word "favn" meaning emracing a pair of arms or a pair of oustretched hands.

The fathom is mostly used in the nautical world to describe depths of water.
