µΩ·cm = Ω·m × 100000000
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 Microohm-centimetres
The microohm-centimetre (µΩ·cm) equals 10⁻⁸ Ω·m = 10 nΩ·m, the traditional unit for bulk metal resistivity in materials science. Copper is 1.68 µΩ·cm; tungsten 5.6 µΩ·cm; platinum 10.6 µΩ·cm; CRC Handbook tables still list metal resistivities in µΩ·cm. 1 µΩ·cm = 10⁻⁸ Ω·m = 10 nΩ·m.
