Convert Ohm Metres to Megaohm Centimetres
1 ohm metre (Ω·m) = 0.0001 megaohm centimetres (MΩ·cm). 1 MΩ·cm = 10000 Ω·m. Example: 15 Ω·m = 15 × 0.0001 = 0.0015 MΩ·cm.

How to Convert Ohm Metre to Megaohm Centimetre
- 1 Ω·m = 0.0001 MΩ·cm
- 1 MΩ·cm = 10000 Ω·m
- Example: convert 15 Ω·m to MΩ·cm: 15 Ω·m = 15 × 0.0001 MΩ·cm = 0.0015 MΩ·cm
Formula
MΩ·cm = Ω·m ÷ 10000
Derivation from SI units:
- The SI unit of electrical resistivity: resistance (Ω) × cross-section (m²) ÷ length (m)
- 1 MΩ·cm = 10⁶ Ω·cm = 10⁴ Ω·m
Both units are defined exactly, so the factor is exact. Ohm Metre definition: ohm metre; Megaohm Centimetre definition: megaohm centimetre.
Worked examples
- A reading of 1e-7 Ω·m converts to 1 × 10⁻¹¹ MΩ·cm.
1e-7 Ω·m × 0.0001 = 1 × 10⁻¹¹ MΩ·cm - A value of 1 Ω·m is 0.0001 MΩ·cm.
1 Ω·m × 0.0001 = 0.0001 MΩ·cm

Where it's used
Ohm Metres are used for conductor and alloy data sheets, while megaohm centimetres appear in ultrapure and deionised water (18.2 MΩ·cm). Both measure electrical resistivity, so the conversion is a fixed factor.

Frequently asked questions
How many megaohm centimetres are in 1 ohm metre?
1 Ω·m = 0.0001 MΩ·cm.
How do I convert ohm metres to megaohm centimetres?
Multiply the value in Ω·m by 0.0001, or divide it by 10000. For example, 15 Ω·m × 0.0001 = 0.0015 MΩ·cm.
Is the Ω·m to MΩ·cm conversion exact?
Yes. Both units are defined exactly, and 1 Ω·m is exactly 0.0001 MΩ·cm.
