Convert Ohm Metres to Microohm Metres
1 ohm metre (Ω·m) = 1000000 microohm metres (µΩ·m). 1 µΩ·m = 0.000001 Ω·m. Example: 15 Ω·m = 15 × 1000000 = 15000000 µΩ·m.

How to Convert Ohm Metre to Microohm Metre
- 1 Ω·m = 1000000 µΩ·m
- 1 µΩ·m = 0.000001 Ω·m
- Example: convert 15 Ω·m to µΩ·m: 15 Ω·m = 15 × 1000000 µΩ·m = 15000000 µΩ·m
Formula
µΩ·m = Ω·m × 1000000
Derivation from SI units:
- The SI unit of electrical resistivity: resistance (Ω) × cross-section (m²) ÷ length (m)
- 1 µΩ·m = 10⁻⁶ Ω·m = 1 Ω·mm²/m
Both units are defined exactly, so the factor is exact. Ohm Metre definition: ohm metre; Microohm Metre definition: microohm metre.
Worked examples
- A reading of 1e-7 Ω·m converts to 0.1 µΩ·m.
1e-7 Ω·m × 1000000 = 0.1 µΩ·m - A value of 1 Ω·m is 1000000 µΩ·m.
1 Ω·m × 1000000 = 1000000 µΩ·m

Where it's used
Ohm Metres are used for conductor and alloy data sheets, while microohm metres appear in resistance and heating alloys. Both measure electrical resistivity, so the conversion is a fixed factor.
