Mu Symbol Meaning in Science & Mathematics
The Greek letter Mu (μ) carries significant meaning across multiple scientific disciplines.
Statistics — Population Mean
In statistics, μ represents the population mean — the average value of an entire population. This differs from x̄ (x-bar), which is a sample mean.
Physics — Friction & Permeability
In physics, μ represents the coefficient of friction, magnetic permeability (μ₀), and the muon particle, among other quantities.
Mathematics — Measure Theory
In math, μ represents a measure in integration theory, the Möbius function μ(n) in number theory, and integrating factors in calculus.
Chemistry — Micro-Units
Chemists use μ for bridging ligands (μ-), chemical potential, and micro-units like micromolar (μM), microgram (μg), and microliter (μL).
Micro Symbol (µ) — Value & Uses
Understanding the micro prefix and its relationship to the Greek letter Mu.
Micro Symbol Value
One millionth (0.000001) of a base unit.
μ vs µ Difference
μ (U+03BC) is Greek Mu. µ (U+00B5) is the dedicated micro sign.
Common Uses
Micrometers, micrograms, microliters, microseconds, and more.

Mu vs. Micro vs. "Mew" — What's the Difference?
These three terms cause frequent confusion. Here's a clear breakdown.
Mu (Greek Letter)
The 12th letter of the Greek alphabet. Unicode: U+03BC. Used in math, physics, and as a general-purpose symbol.
Micro Sign
A separate Unicode character (U+00B5) created for the SI micro prefix. Visually identical to mu. Exists for legacy encoding.
Common Misspelling
Not a real symbol name. People write "mew" because mu is pronounced /mjuː/. The correct spelling is mu.
Bottom line: If you searched for "mew symbol," you're looking for the mu symbol (μ). For everyday copy-paste use, both μ (U+03BC) and µ (U+00B5) work interchangeably. For strict scientific typography, use the Greek mu for mathematical variables and the micro sign for SI unit prefixes.
Common Units Using the Mu (Micro) Symbol
The micro prefix μ means one millionth (10⁻⁶). Here are the most common units.
| Unit | Symbol | Meaning |
|---|---|---|
| Micrometer | μm | One millionth of a meter |
| Microgram | μg | One millionth of a gram |
| Microliter | μL | One millionth of a liter |
| Microsecond | μs | One millionth of a second |
| Micromolar | μM | One millionth of a mole per liter |
| Microvolt | μV | One millionth of a volt |
| Microfarad | μF | One millionth of a farad |
| Microtesla | μT | One millionth of a tesla |
| Microampere | μA | One millionth of an ampere |

Frequently Asked Questions
Common questions about the Mu symbol, micro symbol, and Greek letters.
How do I copy and paste the mu symbol?
Click the μ symbol at the top of this page to instantly copy it to your clipboard. Then paste it anywhere using Ctrl+V (Windows) or Cmd+V (Mac). You can also use the floating copy button in the bottom-right corner.
What is the Alt code for the mu symbol?
On Windows, hold Alt and type 230 on the numeric keypad to get the micro sign (µ). For the Greek mu (μ), use Alt+956. Num Lock must be on, and you must use the keypad — not the number row.
Is μ (mu) the same as µ (micro sign)?
They look nearly identical but are different Unicode characters. The Greek Small Letter Mu is U+03BC, while the Micro Sign is U+00B5. The micro sign was added for backward compatibility. In practice, both work the same in documents and on the web.
What does the mu symbol mean in physics?
In physics, μ represents the coefficient of friction (μₛ for static, μₖ for kinetic), magnetic permeability (μ₀ = 4π × 10⁻⁷ H/m), the muon elementary particle, and the micro prefix (10⁻⁶) used in units like μm, μs, and μF.
What does μ mean in statistics?
In statistics, μ represents the population mean — the average value of an entire population. This is different from x̄ (x-bar), which represents the sample mean. The formula is μ = Σx / N, where N is the total population size.
Why do people spell mu as "mew"?
The Greek letter μ is pronounced /mjuː/ ("myoo") in English, which sounds like "mew." This phonetic similarity leads to the common misspelling. The correct spelling is mu. If you searched for "mew symbol," you've found the right page — the symbol you need is μ.
How do I type mu on a Mac?
Press Option+M to type the micro sign (µ). For the exact Greek mu, press Control+Command+Space to open the Character Viewer and search for "mu."
What is the HTML code for the mu symbol?
Use μ or μ for the Greek lowercase mu (μ). For the micro sign, use µ or µ. In CSS, use \03BC for mu or \00B5 for the micro sign.
What is the value of the micro prefix?
The micro prefix (μ) represents 10⁻⁶, which is one millionth (0.000001) of a unit. For example: 1 μm = 0.000001 meters, 1 μg = 0.000001 grams, 1 μs = 0.000001 seconds.
What is the name of the μ symbol?
The symbol μ is called "Mu" (pronounced "myoo"). It is the 12th letter of the Greek alphabet. The uppercase version is Μ (looks like Latin M), and the lowercase is μ. In scientific contexts, it's often called the "micro symbol" when used as a prefix.
