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".

Micrometre

Symbol: μm
Unit System: SI

What is the Micrometre?

The micrometre (American spelling micrometer) is a unit of length and is a multiple of the SI unit metre. It uses the symbol μm.

It represents one millionth of a metre and is also known by its previously depreciated name micron.

In the US, the term 'micron' helped distinguish the unit name from the device 'micrometer' but the International System of Units (SI) discontinued this term in favour of micrometre as the prefix system required the use of the Greek symbol 'μ' which invoked the factor x10−6.
