what does the symbol µ mean?

Answer 1

Case 1: symbols sometimes used for the micrometer (micron). The symbol um is acceptable in situations where the Greek letter mu (µ) is not available to make the proper symbol µm. However, the "plural" symbol ums is never acceptable, because the SI prohibits adding -s to a symbol to form a plural.

Case2: The symbol μ (Greek: mu) is used to denote the arithmetic mean of an entire population. Or, for a random number that has a defined mean, μ is the probabilistic mean or expected value of the random number.

------------------------
The lower-case letter mu is used as a special symbol in many academic fields. The upper case Mu isn't generally used in this way because it is normally indistinguishable from the Latin M.

* In mathematics:
- the Möbius function in number theory
- the population mean or expected value in probability and statistics
- a measure in measure theory
* In measurement:
- the SI prefix micro-, which represents one millionth, or 10E-6 Unicode actually encodes the micro sign separately from the Greek letter though they look identical in most fonts.
- the micron, an old unit which corresponds to the micrometre (which is now denoted "µm")
* In classical physics and engineering:
- the coefficient of friction
- reduced mass in the two-body problem
- permeability in electromagnetism
- dynamic viscosity in fluid mechanics
* In particle physics:
- the elementary particle called the muon

Answer 2

Um Symbol

Answer 3

Micro sign (µ, ) is the Unicode character U+00B5. It serves as a symbol for the SI prefix "micro"; it is the only non-Latin character used for an SI prefix. Micro sign is derived from the small Greek letter mu (μ), The two may or may not look the same, depending on the font. The HTML representation for it is µ (whereas mu is represented as μ).

Answer 5

Mu (uppercase Μ, lowercase μ) is the 12th letter of the Greek alphabet. In the system of Greek numerals it has a value of 40. It was derived from the Phoenician letter Mem Mem. Letters that arose from Mu include the Roman M and the Cyrillic letter Em (М, м).

The word mu (pronounced /mju/ ["mew" or "myoo"]) is written μῦ in traditional Greek polytonic orthography. In Modern Greek it is sometimes written μι (mi).

Mu was derived from the Egyptian hieroglyphic symbol for water (The hieroglyph n) which had been simplified by the Phoenicians and named after their word for water, mem.

The letter mu appears in conjunction with alpha and omega to signify the "beginning, middle (meson) and end", a phrase found in an Orphic verse describing Zeus, and later adopted to describe both Jehovah and Jesus.

In Aeschylus' Eumenides, the repeated moaning of the letter mu is the sound made by the sleeping Furies as the ghost of Clytemnestra begins to invoke them. It again appears as an ominous mantra in a 10th century Coptic papyrus, containing a Christian curse against perjurers that invokes the angel Temeluchos:

I adjure you by the seven perfect letters, ΜΜΜΜΜΜΜ. You must appear to him, you must appear to him. I adjure you by the seven angels around the throne of the father.

Answer 6

The symbol does mean "micro" as in micrometer but the value is 0.000001 of a METER, not a decameter.

Answer 7

In magnetism, that symbol mean Magnetic permiability.Which tells how much a material can permit the magnetic lines of fource.

Answer 8

It can be a prefix for metric units and it stands for micro-. E.g. µm = micrometres (commonly known as microns). It means 1/1,000,000 of the unit. E.g. a micrometre is 1/1,000,000 of a metre.

Answer 9

It means "micro-" as in "micrometer." It's 10^-6 of a meter, one level below millimeter (10^-3).

Answer 10

in unit measure that symbol means micro or 1E-6.
