Mu

The $12$th letter of the Greek alphabet.

Minuscule: $\mu$

Majuscule: $\Mu$

The $\LaTeX$ code for \(\mu\) is \mu .

The $\LaTeX$ code for \(\Mu\) is \Mu .

micro-

$\mu$

The Système Internationale d'Unités symbol for the metric scaling prefix micro, denoting $10^{\, -6}$, is $\mu$.

Micron

$\mu$

Before $1967$, the micrometre $\mu \mathrm m$ was called the micron.

Its symbol was $\mu$.

Its $\LaTeX$ code is \mu .

Expectation

$\mu$

Often used to denote the expectation of a given random variable.

Linear Density

$\mu$

Used to denote the linear density of a given one-dimensional body:

$\mu = \dfrac m l$

where:

$m$ is the body's mass;

$l$ is the body's length.

Poisson Distribution

$\mu$

Used as an alternative to $\lambda$ to denote the parameter of a given Poisson distribution.

Moment of Discrete Random Variable

$\mu'_n$

Let $X$ be a discrete random variable.

Then the $n$th moment of $X$ is denoted $\mu'_n$ and defined as:

$\mu'_n = \expect {X^n}$

where $\expect {\, \cdot \,}$ denotes the expectation function.

The $\LaTeX$ code for \(\mu'_n\) is \mu'_n .

Micrometre

$\mu \mathrm m$

The symbol for the micrometre is $\mu \mathrm m$.

$\mu$ for micro

$\mathrm m$ for metre.

Its $\LaTeX$ code is \mu \mathrm m .
