Conversion Formula
Ω·m = Ω·cm × 0.01
About Ohm-centimetres
The ohm-centimetre (Ω·cm) equals 0.01 Ω·m, the most widely used unit for semiconductor resistivity in device characterisation. Silicon wafers are specified in Ω·cm: lightly doped n-type Si is 100-10 000 Ω·cm; device-grade p-type Si is 1-50 Ω·cm; germanium is ≈0.46 Ω·cm. ASTM F84 and SEMI standards define silicon resistivity measurements in Ω·cm. 1 Ω·cm = 0.01 Ω·m.
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.
