Conversion Formula
fH/m = µH/m × 1000000000
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 Femtohenries per metre
The femtohenry per metre (fH/m) equals 10⁻¹⁵ H/m. A theoretical subunit used in precision electromagnetic metrology. Even the extreme diamagnet bismuth (µᵣ = 0.999834) departs from µ₀ by about −207 nH/m - far above the fH/m scale. Primarily a reference unit for quantum EM standard calculations. 1 fH/m = 10⁻¹⁵ H/m.
