Convert Vacuum permeabilities to Kilohenries per metre
Convert Vacuum permeabilities (µ₀) to Kilohenries per metre (kH/m) instantly and accurately.
Conversion Formula
kH/m = µ₀ × 1.256637061e-9
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.
About Kilohenries per metre
The kilohenry per metre (kH/m) equals 10³ H/m ≈ 7.96 × 10⁸ µ₀. A theoretical reference scale beyond any known bulk magnetic material: achieving kH/m would require µᵣ ≳ 10⁹, far exceeding the highest measured value (~10⁶ for Supermalloy). Used as an upper bound in theoretical magnetics. 1 kH/m = 10³ H/m.
