Unit Information

Inch
/ɪn(t)ʃ/
Symbol: in
Unit System: Imperial

What is the Inch?

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

There are 12 inches in a foot and 3 feet in a yard. Therefore there are 36 inches in a yard. There are exactly 2.54 centimetres in an inch.

Borrowed from the Latin 'uncia' - the English word 'inch', the origination of the word came from the Old English word for 'ounce' which was related to the Roman phrase for "one twelfth".

The inch is still a commonly used unit in the UK, USA and Canada - and is also still used in the production of electronic equipment, still very evident in the measuring of monitor and screen sizing.

Micrometre
/ˈmʌɪkrə(ʊ)ˌmiːtə/
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.
