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

How to Convert Microohm Centimetre to Ohm Metre
- 1 µΩ·cm = 1 × 10⁻⁸ Ω·m
- 1 Ω·m = 100000000 µΩ·cm
- Example: convert 1.72 µΩ·cm to Ω·m: 1.72 µΩ·cm = 1.72 × 1 × 10⁻⁸ Ω·m = 1.72 × 10⁻⁸ Ω·m
Formula
Ω·m = µΩ·cm ÷ 100000000
Derivation from SI units:
- 1 µΩ·cm = 10⁻⁸ Ω·m = 10 nΩ·m
- The SI unit of electrical resistivity: resistance (Ω) × cross-section (m²) ÷ length (m)
Both units are defined exactly, so the factor is exact. Microohm Centimetre definition: microohm centimetre; Ohm Metre definition: ohm metre.
Worked examples
- Copper at 1.72 µΩ·cm is 1.72 × 10⁻⁸ Ω·m.
1.72 µΩ·cm × 1 × 10⁻⁸ = 1.72 × 10⁻⁸ Ω·m - Stainless steel 304 at about 72 µΩ·cm is 7.2 × 10⁻⁷ Ω·m.
72 µΩ·cm × 1 × 10⁻⁸ = 7.2 × 10⁻⁷ Ω·m
