Convert Ohm Centimetres to Megaohm Centimetres
1 ohm centimetre (Ω·cm) = 0.000001 megaohm centimetres (MΩ·cm). 1 MΩ·cm = 1000000 Ω·cm. Example: 15 Ω·cm = 15 × 0.000001 = 0.000015 MΩ·cm.

How to Convert Ohm Centimetre to Megaohm Centimetre
- 1 Ω·cm = 0.000001 MΩ·cm
- 1 MΩ·cm = 1000000 Ω·cm
- Example: convert 15 Ω·cm to MΩ·cm: 15 Ω·cm = 15 × 0.000001 MΩ·cm = 0.000015 MΩ·cm
Formula
MΩ·cm = Ω·cm ÷ 1000000
Derivation from SI units:
- 1 Ω·cm = 0.01 Ω·m
- 1 MΩ·cm = 10⁶ Ω·cm = 10⁴ Ω·m
- 1 Ω·cm = 0.01 Ω·m ÷ 10000 Ω·m per MΩ·cm = 0.000001 MΩ·cm
Both units are defined exactly, so the factor is exact. Ohm Centimetre definition: ohm centimetre; Megaohm Centimetre definition: megaohm centimetre.
Worked examples
- A reading of 10 Ω·cm converts to 0.00001 MΩ·cm.
10 Ω·cm × 0.000001 = 0.00001 MΩ·cm - A value of 5000 Ω·cm is 0.005 MΩ·cm.
5000 Ω·cm × 0.000001 = 0.005 MΩ·cm

Where it's used
Ohm Centimetres are used for silicon wafer resistivity (for example 1–10 Ω·cm), 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 centimetre?
1 Ω·cm = 0.000001 MΩ·cm.
How do I convert ohm centimetres to megaohm centimetres?
Multiply the value in Ω·cm by 0.000001, or divide it by 1000000. For example, 15 Ω·cm × 0.000001 = 0.000015 MΩ·cm.
Is the Ω·cm to MΩ·cm conversion exact?
Yes. Both units are defined exactly, and 1 Ω·cm is exactly 0.000001 MΩ·cm.
