## 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.

League

Symbol: leagues
Unit System: None

### What is the League?
