You can do the reverse unit conversion from astronomical unit to millimicron, or enter any two units below:
millimicron to pouce
millimicron to terameter
millimicron to range
millimicron to hand
millimicron to pertica
millimicron to metric mile
millimicron to megameter
millimicron to moot
millimicron to fist
millimicron to decameter
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
The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length. It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles).
The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".
