Convert Ohm Metres to Microohm Centimetres
1 ohm metre (Ω·m) = 100000000 microohm centimetres (µΩ·cm). 1 µΩ·cm = 1 × 10⁻⁸ Ω·m. Example: 0.0000000172 Ω·m = 0.0000000172 × 100000000 = 1.72 µΩ·cm.

How to Convert Ohm Metre to Microohm Centimetre
- 1 Ω·m = 100000000 µΩ·cm
- 1 µΩ·cm = 1 × 10⁻⁸ Ω·m
- Example: convert 0.0000000172 Ω·m to µΩ·cm: 0.0000000172 Ω·m = 0.0000000172 × 100000000 µΩ·cm = 1.72 µΩ·cm
Formula
µΩ·cm = Ω·m × 100000000
Derivation from SI units:
- The SI unit of electrical resistivity: resistance (Ω) × cross-section (m²) ÷ length (m)
- 1 µΩ·cm = 10⁻⁸ Ω·m = 10 nΩ·m
Both units are defined exactly, so the factor is exact. Ohm Metre definition: ohm metre; Microohm Centimetre definition: microohm centimetre.
Worked examples
- Aluminium at 0.0000000265 Ω·m is 2.65 µΩ·cm.
0.0000000265 Ω·m × 100000000 = 2.65 µΩ·cm - Iron at about 0.000000097 Ω·m is 9.7 µΩ·cm.
0.000000097 Ω·m × 100000000 = 9.7 µΩ·cm

Frequently asked questions
Why is µΩ·cm used for metals?
Metal resistivities in Ω·m are around 10⁻⁸, so µΩ·cm gives simple numbers: copper 1.72, aluminium 2.65.
How many microohm centimetres are in 1 ohm metre?
1 Ω·m = 100000000 µΩ·cm.
How do I convert ohm metres to microohm centimetres?
Multiply the value in Ω·m by 100000000. For example, 0.0000000172 Ω·m × 100000000 = 1.72 µΩ·cm.
Is the Ω·m to µΩ·cm conversion exact?
Yes. Both units are defined exactly, and 1 Ω·m is exactly 100000000 µΩ·cm.
