Convert Microohm Metres to Ohm Square Millimetres per Metre
1 microohm metre (µΩ·m) = 1 ohm square millimetre per metre (Ω·mm²/m). 1 Ω·mm²/m = 1 µΩ·m. Example: 15 µΩ·m = 15 × 1 = 15 Ω·mm²/m.

How to Convert Microohm Metre to Ohm Square Millimetre per Metre
- 1 µΩ·m = 1 Ω·mm²/m
- 1 Ω·mm²/m = 1 µΩ·m
- Example: convert 15 µΩ·m to Ω·mm²/m: 15 µΩ·m = 15 × 1 Ω·mm²/m = 15 Ω·mm²/m
Formula
Ω·mm²/m = µΩ·m × 1
Derivation from SI units:
- 1 µΩ·m = 10⁻⁶ Ω·m = 1 Ω·mm²/m
- 1 Ω·mm²/m = 10⁻⁶ Ω·m (resistance in Ω of a 1 m wire with 1 mm² cross-section)
- 1 µΩ·m = 0.000001 Ω·m ÷ 0.000001 Ω·m per Ω·mm²/m = 1 Ω·mm²/m
Both units are defined exactly, so the factor is exact. Microohm Metre definition: microohm metre; Ohm Square Millimetre per Metre definition: ohm square millimetre per metre.
Worked examples
- A reading of 0.1 µΩ·m converts to 0.1 Ω·mm²/m.
0.1 µΩ·m × 1 = 0.1 Ω·mm²/m - A value of 1 µΩ·m is 1 Ω·mm²/m.
1 µΩ·m × 1 = 1 Ω·mm²/m

Where it's used
Microohm Metres are used for resistance and heating alloys, while ohm square millimetres per metre appear in cable and wire resistance (R = ρ × length ÷ mm²). Both measure electrical resistivity, so the conversion is a fixed factor.
