In the number system, mu (μ) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth).
The symbol is also used to denote magnetic permeability, which is a representation of how much a substance concentrates magnetic lines of flux.
The sign may be formed in most IBM-compatible computers by using the NUM LOCK feature, holding down the ALT key, and then inputting 230 on the keypad at the right-hand end of the keyboard while holding down the ALT key. When you release ALT after entering these digits, the sign displays. This is supported by practically all Windows-based word processors, as well as certain DOS products.
Uses of mu (µ ) in Science
| Number | Use of µ in Science |
| 1 | The magnetic permeability of material in physics |
| 2 | The chemical potential of a substance in chemistry |
| 3 | The growth rate of microorganisms in microbiology |
| 4 | Variable or constant in equations and formulas in mathematics, particularly in statistics and probability theory |
Examples of Mu (µ) in Science
| No. | Examples of Mu (µ) in Science | Formulas/Equations |
| 1. | The magnetic permeability of free space | µ = 4π x 10^-7 H/m |
| 2. | The magnetic field of a current-carrying wire | B = (µI/2πr) |
| 3. | Dynamic viscosity in fluid mechanics | τ = µ (du/dy), where τ is shear stress and du/dy is the velocity gradient |
| 4. | Particle magnetic moment in quantum mechanics | μ = γ x L, where γ is the gyromagnetic ratio and L is the angular momentum |
| 5. | Coefficient of friction in materials science | Ff = μFn, where Ff is the force of friction, Fn is the normal force, and μ is the coefficient of friction |
| 6. | Magnetic susceptibility in materials science | χm = µr – 1, where µr is the relative permeability of the material |
| 7. | Mean or reduced magnetic moment in statistical mechanics | µ = (gjμjB)/kT, where gj is the degeneracy factor, μj is the magnetic moment of the jth energy level, B is the magnetic field, k is the Boltzmann constant, and T is the temperature. |
