## Unit Information

Mile
/mʌɪl/
Symbol: mi
Unit System: Imperial

### What is the Mile?

The mile is a unit of length in the imperial unit system with the symbol mi.

It was originally an English unit but was adopted by many countries who all had their own slight variation on definition. The English mile, however, is equal to 63,360 inches, 5280 ft or 1760 yards.

The UK still uses the mile on all roadway signs rather than the kilometre; its SI "equivalent". It used to have the symbol 'm' until SI was established and it was changed to avoid confusion with the unit metre.

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.
