How to convert magnetic permeability
Magnetic permeability tells how easily a material supports a magnetic field. The vacuum permeability μ₀ is about 1.2566 × 10⁻⁶ H/m.
Every magnetic permeability unit is a fixed multiple of one base unit, the H/m. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert µH/m to μ₀, multiply by 0.7957747150. To go the other way, divide by 0.7957747150.
The converter above does this for you and shows the exact formula under the result.
