Convert Kiloohm Centimetres to Ω·mm²/m

Formula

Ω·mm²/m = kΩ·cm × 10000000

Derivation from SI units:

• 1 kΩ·cm = 1000 Ω·cm = 10 Ω·m
• 1 Ω·mm²/m = 10⁻⁶ Ω·m (resistance in Ω of a 1 m wire with 1 mm² cross-section)
• 1 kΩ·cm = 10 Ω·m ÷ 0.000001 Ω·m per Ω·mm²/m = 10000000 Ω·mm²/m

Both units are defined exactly, so the factor is exact. Kiloohm Centimetre definition: kiloohm centimetre; Ohm Square Millimetre per Metre definition: ohm square millimetre per metre.

Worked examples

1. A reading of 5 kΩ·cm converts to 50000000 Ω·mm²/m.
   5 kΩ·cm × 10000000 = 50000000 Ω·mm²/m
2. A value of 50 kΩ·cm is 500000000 Ω·mm²/m.
   50 kΩ·cm × 10000000 = 500000000 Ω·mm²/m

Where it's used

Kiloohm Centimetres are used for soil resistivity surveys, 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.
