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 Gigaohm-metres
The gigaohm-metre (GΩ·m) equals 10⁹ Ω·m, the scale for excellent insulating materials and ultra-pure liquids. Fused silica (quartz glass) has resistivity ≈ 10⁴-10⁵ GΩ·m at room temperature; ultra-pure deionised water is ≈18 MΩ·cm = 180 kΩ·m; synthetic sapphire is ≈1-10⁴ GΩ·m depending on temperature. 1 GΩ·m = 10⁹ Ω·m = 10³ MΩ·m.
