Relative permeability to henries per meter
Type a value in μr to get it in H/m instantly.
0.005027H/m
That's about the same as electrical steel.
Convert the other way: H/m to μr
What it means
How strongly does it gather field?
Figures for iron and alloys are typical maximum or initial values. Real permeability changes with field strength, frequency and temperature.
The math
How to convert μr to H/m
To convert relative permeability to henries per meter, multiply by 1.257×10⁻⁶.
Example: 4,000 μr × 1.257×10⁻⁶ = 0.00502655 H/m.
In the other direction, 1 H/m = 795,775 μr.
