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 Megaohm-metres
The megaohm-metre (MΩ·m) equals 10⁶ Ω·m, the scale for polymer insulators and high-purity dielectric ceramics. PTFE (Teflon) has resistivity ~10⁷ MΩ·m; polypropylene cable insulation is 10⁴-10⁶ MΩ·m; IEC 60093 surface and volume resistivity measurements on solid insulating materials are quoted in MΩ·m. 1 MΩ·m = 10⁶ Ω·m = 10³ kΩ·m.
