Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.

Convert absolute magnetic permeability (μ) across 10 units in SI prefix forms (H/m, mH/m, μH/m, nH/m, kH/m) and equivalent representations (T·m/A, Wb/(A·m), N/A², V·s/(A·m), μ₀ multiples). μ₀ ≈ 1.2566 μH/m. Reference: iron μᵣ ≈ 5,000–200,000, mu-metal ≈ 50,000. 100% browser-based.

How to Use

  1. 1Type a magnetic permeability value (e.g. 1.2566 for μ₀ in μH/m)
  2. 2Select your starting unit (e.g. μH/m, H/m, T·m/A, μ₀ multiples)
  3. 3Select your target unit - the result appears instantly
  4. 4All 10 conversions appear across SI Prefixes and Equivalent Forms groups
  5. 5Enable Sci notation (recommended for H/m values)
  6. 6Open 'Magnetic permeability reference' for material μᵣ values

Features

  • 10 magnetic permeability units: H/m, mH/m, μH/m, nH/m, kH/m + equivalent forms
  • SI forms and equivalent representations (T·m/A, Wb/(A·m), N/A², V·s/(A·m), μ₀)
  • Reference: μ₀, iron μᵣ, mu-metal, ferrite
  • Scientific notation on by default
  • One-click copy per result
  • 100% browser-based
