Convert Megaohm Centimetres to Ohm Metres
1 megaohm centimetre (MΩ·cm) = 10000 ohm metres (Ω·m). 1 Ω·m = 0.0001 MΩ·cm. Example: 15 MΩ·cm = 15 × 10000 = 150000 Ω·m.

How to Convert Megaohm Centimetre to Ohm Metre
- 1 MΩ·cm = 10000 Ω·m
- 1 Ω·m = 0.0001 MΩ·cm
- Example: convert 15 MΩ·cm to Ω·m: 15 MΩ·cm = 15 × 10000 Ω·m = 150000 Ω·m
Formula
Ω·m = MΩ·cm × 10000
Derivation from SI units:
- 1 MΩ·cm = 10⁶ Ω·cm = 10⁴ Ω·m
- The SI unit of electrical resistivity: resistance (Ω) × cross-section (m²) ÷ length (m)
Both units are defined exactly, so the factor is exact. Megaohm Centimetre definition: megaohm centimetre; Ohm Metre definition: ohm metre.
Worked examples
- A reading of 2 MΩ·cm converts to 20000 Ω·m.
2 MΩ·cm × 10000 = 20000 Ω·m - A value of 15 MΩ·cm is 150000 Ω·m.
15 MΩ·cm × 10000 = 150000 Ω·m
