Unit Information

Ell
/ɛl/
Symbol: ell
Unit System: Historic English

What is the Ell?

The ell is a unit of length and originates from historic England and uses the symbol ell.

The ell usually measured 45in or 1.143m but was origally a "cubit" - which was the length from your elbow to the tip of your fingers and literally translated from the word "arm". It was mostly used in the tailoring world when buying and selling textiles.

Although now obsolete, the word "ell" still survives in the English word "elbow".

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.
