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.
About Milliohm-centimetres
The milliohm-centimetre (mΩ·cm) equals 10⁻⁵ Ω·m, a scale used for poorly conducting alloys and heavily doped semiconductors at low temperature. Graphite perpendicular to the basal plane has resistivity around 3-10 mΩ·cm; hot-pressed sintered tungsten carbide compacts are 0.2-0.5 mΩ·cm; heavily B-doped silicon at degeneracy is ∼0.1 mΩ·cm. 1 mΩ·cm = 10⁻⁵ Ω·m.
