How many micrometer in 1 millimicrons? The answer is 0.001. We assume you are converting between micrometre and millimicron. You can view more details on each measurement unit: micrometer or millimicrons The SI base unit for length is the metre. 1 metre is equal to 1000000 micrometer, or 1000000000 millimicrons. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between micrometres and millimicrons.

You can do the reverse unit conversion from millimicrons to micrometer, or enter any two units below:
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 It is also commonly known as a micron, although that term is officially outdated.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.
The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.
So 1 millimicron = 10-3 microns.
The definition of a micron is as follows:
a metric unit of length equal to one millionth of a meter
