›› Definition: Micrometer

A micrometre (American spelling: micrometer, symbol µm) is an SI unit of length equal to one millionth of a metre, or about a tenth of the size of a droplet of mist or fog. It is also commonly known as a micron, although that term is officially outdated. It can be written in the expanded mathmatical notation (1×10-6 m)

The symbol µ is the "micro sign", which should look identical to the Greek letter mu (?) (the two may or may not look the same, depending on the font). The symbol "um" is sometimes used, when the µ and ? are not available, for example when using a typewriter.

The micrometre is a common unit of measurement for wavelengths of infrared radiation. Some people (especially in astronomy and the semiconductor business) use the old name micron and/or the solitary symbol µ (both of which were official between 1879 and 1967) to denote a micrometre. This practice persists in the face of official discouragement, perhaps to help disambiguate between the unit of measurement and the micrometer, a measuring device.


›› Definition: Chinese inch

The cun (Chinese: 寸; pinyin: cùn; Wade-Giles: ts'un) is a traditional Chinese unit of length. Its traditional measure is the width of a person's thumb at the knuckle, whereas the width of the two forefingers denotes 1.5 cun and the width of all fingers side-by-side is three cuns. In this sense it continues to be used to chart acupuncture points on the human body in various uses of traditional Chinese medicine.

The cun was part of a larger system, and represented one-tenth of a chi (Chinese foot). In time the lengths were standardized, and in Hong Kong, using the traditional standard, it measures ~3.715 cm (~1.463 in). In the twentieth century in the Republic of China, the lengths were standardized to fit with the metric system, and in current usage in China and Taiwan it measures 31⁄3 cm (~1.312 in).
