Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (henry per meter (H/m)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

2. Target SI Bridge (ktarget):1 nH/m = 1 × 10⁻⁹ henry per meter (H/m)
Step-by-step substitution for Vacuum Permeability → Nanohenry/meter:V(nH/m) = V(μ₀) × ( 1.256637 × 10⁻⁶ / 1 × 10⁻⁹ ) = V(μ₀) × 1256.637062
