Conversion Formula
nΩ·m = Ω·m × 1000000000
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 Nanoohm-metres
The nanoohm-metre (nΩ·m) equals 10⁻⁹ Ω·m, the most convenient scale for the resistivity of metals. Silver (1.59), copper (1.68), gold (2.44), and aluminium (2.82) all have bulk room-temperature resistivities expressible as low single-digit nΩ·m values; thin-film interconnect resistance targets in advanced IC nodes are set in nΩ·m. 1 nΩ·m = 10⁻⁹ Ω·m = 0.1 µΩ·cm.
