About Milliohm-metres
The milliohm-metre (mΩ·m) equals 10⁻³ Ω·m, the scale for highly resistive alloys, graphite, and transition-metal oxides. Carbon-graphite brushes used in DC motors have resistivity of 20-100 mΩ·m; ferrites used in power magnetics are 0.1-10 mΩ·m; polyaniline conducting polymer films are in the mΩ·m range when fully protonated. 1 mΩ·m = 10⁻³ Ω·m = 10 Ω·cm.
About Ohm circular mil per foot
The ohm circular mil per foot (Ω·cmil/ft) is the US customary resistivity unit for wires and cables, equal to π×6.4516×10⁻¹⁰/(4×0.3048) Ω·m ≈ 1.66243×10⁻⁹ Ω·m. Copper has resistivity ≈1.012 Ω·cmil/ft; wire tables in NFPA 70 (NEC) and ASTM B3 list conductor resistivity in this unit. 1 Ω·cmil/ft ≈ 1.66243 nΩ·m.
