microm

Microm is a term that can refer to more than one thing, and there is no single canonical meaning. In measurement language, microm may appear as a nonstandard shorthand for micrometer, the SI-derived unit equal to one millionth of a meter. The standard spelling is micrometre in British English or micrometer in American English, and the symbol is μm. In contemporary technical writing, microm is uncommon outside legacy texts or informal notes.

Microm is also used as a brand name or model designation by various manufacturers, particularly in fields associated with precision engineering, optics, or microfabrication. Because it is not unique to a specific company, any reference to Microm should be clarified with context such as the company name, product category, and region to avoid confusion.

In fiction and media, Microm can function as a proper noun—used for fictional corporations, technologies, or places. In such cases, the meaning depends on the work.

Related terms include micrometer and micrometre, the standard units of length; and the prefix micro-, used to denote one millionth part. The term "Microm" is not a standard SI term on its own.
