About Microhenries per metre
The microhenry per metre (µH/m) equals 10⁻⁶ H/m. The most practical scale for absolute permeability: vacuum permeability µ₀ ≈ 1.257 µH/m, so all non-magnetic materials (air, plastics, biological tissue) have µ between 1.256 and 1.258 µH/m. Relative permeability is simply µᵣ = µ / 1.257 µH/m. 1 µH/m = 10⁻⁶ H/m.
About Vacuum permeabilities
The vacuum permeability (µ₀), also called the magnetic constant, equals 4π × 10⁻⁷ H/m ≈ 1.25664 µH/m. In the 2019 SI it is experimentally determined: µ₀ = 1.25663706212(19) × 10⁻⁶ H/m. The absolute permeability of any material is µ = µᵣ × µ₀. 1 µ₀ = 4π × 10⁻⁷ H/m.
