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.

What is the Fathom?

The fathom is a unit of length in the imperial unit system and uses the symbol ftm.

One fathom is equal to 6 feet or 1.8288m.

The phrase fathom derives from an old English derivative of a Viking / Danish word "favn" meaning emracing a pair of arms or a pair of oustretched hands.

The fathom is mostly used in the nautical world to describe depths of water.
