Unit Information

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.

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.
