Micro (Greek letter μ, mu, non-italic) is a unit prefix in the metric system denoting a factor of 10 −6 (one millionth). [1] It comes from the Greek word μικρός (mikrós), meaning "small". [2] It is the only SI prefix which uses a character not from the Latin alphabet.
A monitor unit (MU) is a measure of machine output from a clinical accelerator for radiation therapy such as a linear accelerator or an orthovoltage unit. Monitor units are measured by monitor chambers, which are ionization chambers that measure the dose delivered by a beam and are built into the treatment head of radiotherapy linear accelerators.
The micrometre (Commonwealth English as used by the International Bureau of Weights and Measures; [1] SI symbol: μm) or micrometer (American English), also commonly known by the non-SI term micron, [2] is a unit of length in the International System of Units (SI) equalling 1 × 10 −6 metre (SI standard prefix "micro-" = 10 −6); that is, one millionth of a metre (or one thousandth of a ...

A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic.Each prefix has a unique symbol that is prepended to any unit symbol.
In electromagnetism, permeability is the measure of magnetization produced in a material in response to an applied magnetic field.Permeability is typically represented by the (italicized) Greek letter μ.
The lumerg is a unit of luminous energy equal to 10 −7 lumen-seconds (100 nlm s). The talbot (T) is a unit of luminous energy equal to one lumen-second (1 lm⋅s). The einstein (E) has two conflicting definitions. The original is a unit of energy, equal to the energy in one mole (1 mol) of photons.
