Conversion Formula
Ω·m = mΩ·m × 0.001
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-metres
The ohm-metre (Ω·m) is the SI coherent unit of electrical resistivity, equal to 1 V·m/A = 1 kg·m³·A⁻²·s⁻³. Seawater is ≈0.2 Ω·m; deionised water is ~18 MΩ·cm = 180 kΩ·m; silicon carbide ≈0.1-10 Ω·m; IEC 60287 specifies cable insulation resistivity in Ω·m. 1 Ω·m = 10² Ω·cm = 10⁶ µΩ·m.
