It may refer to the Greek letter mu. It looks like a "u", with the left vertical line extended down (more or less like an upside-down "h"), and means "micro", a multiplier of 1/1,000,000. For example, a micrometer is a millionth of a meter (or a thousandth of a millimeter).
If you have trouble typing the letter "mu", you can substitute the letter "u".
"ul" might refer to microliter, same as cubic millimeter. When there are technical difficulties to show the "mu" symbol, it may be replaced by the letter "u", which looks somewhat similar.
So I believe you are asking about the Moebius or Möbius Mu(n) function. This is a number theoretic function defined as follows:Mu(n) = 0 if n has one or more repeated prime factors Mu(n) = 1 if n = 1 Mu(n) = (−1)^k if n is the product of k distinct primes Mu(n) = Mu(−n), (Mu(n) is not normally defined for n < 1) Mu(0) = 0So the answer to your question is mu of zero is 0Dr. ChuckHowever, if you are looking for the value of mu subscript 0, μ₀ that equals 4(pi) x 10^-7 T m/Aμ₀ = 4π x 10^-7 T m/A
If the 3 is raised, it means m to the third power. If it's a measurement, it may mean cubic meters.
You can find the character for mu most easily by searching for it on the internet, then copying and pasting it wherever you need.
z = (x-mu)/sigma So x = sigma*z + mu = 3m*(-3) + 25 = -9m + 25
The Greek letter μ, which is the symbol for the coefficient of friction, or the prefix micro-
MG stands for milligrams in measurement.
tsp in measurement stands for teaspoon.
hectare
Unit of Measurement

decimeter
hg is a measurement of Vacuum measured in Inches of Murcury.
It could be the Greek letter "mu", which stands for micro = 1 millionth.
In some cases MUS stands for Montecito Union School.
If you're in motorola land. It's an abbreviation for Mobile Unit.
