Convert Milliohm-metres to Ohm-centimetres
Convert Milliohm-metres (mΩ·m) to Ohm-centimetres (Ω·cm) instantly and accurately.
Conversion Formula
Ω·cm = mΩ·m × 0.1
About Milliohm-metres
The milliohm-metre (mΩ·m) equals 10⁻³ Ω·m, the scale for highly resistive alloys, graphite, and transition-metal oxides. Carbon-graphite brushes used in DC motors have resistivity of 20-100 mΩ·m; ferrites used in power magnetics are 0.1-10 mΩ·m; polyaniline conducting polymer films are in the mΩ·m range when fully protonated. 1 mΩ·m = 10⁻³ Ω·m = 10 Ω·cm.
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.
