Conversion Formula
µΩ·m = Ω·cm × 10000
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 Microohm-metres
The microohm-metre (µΩ·m) equals 10⁻⁶ Ω·m and is numerically identical to 1 Ω·mm²/m used in the cable industry. Nichrome resistance wire has resistivity ≈1.0-1.1 µΩ·m; stainless steel is 0.69-0.72 µΩ·m; manganin alloy (for precision shunts) is about 0.48 µΩ·m. 1 µΩ·m = 10⁻⁶ Ω·m = 1 Ω·mm²/m.
