Convert Ohm-centimetres to Megaohm-metres
Convert Ohm-centimetres (Ω·cm) to Megaohm-metres (MΩ·m) instantly and accurately.
Conversion Formula
MΩ·m = Ω·cm × 1.000000000e-8
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 Megaohm-metres
The megaohm-metre (MΩ·m) equals 10⁶ Ω·m, the scale for polymer insulators and high-purity dielectric ceramics. PTFE (Teflon) has resistivity ~10⁷ MΩ·m; polypropylene cable insulation is 10⁴-10⁶ MΩ·m; IEC 60093 surface and volume resistivity measurements on solid insulating materials are quoted in MΩ·m. 1 MΩ·m = 10⁶ Ω·m = 10³ kΩ·m.
