## Unit Information

Foot
/fʊt/
Symbol: ft
Unit System: Imperial

### What is the Foot?

The foot is a unit of length in the imperial unit system and uses the symbol ft.

One foot is exactly equal to 12 inches. It is also exactly equal to 0.3048m. One yard is comprised of three feet.

The foot is just behind the metre in terms of widespread use due to its previous popularity. The US is the only developed country that still uses the foot in preference to the metre.

The UK still uses feet to express human height more than metres.

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.
