Convert Siemens per Metre to Millisiemens per Centimetre
1 siemens per metre (S/m) = 10 millisiemens per centimetre (mS/cm). 1 mS/cm = 0.1 S/m. Example: 15 S/m = 15 × 10 = 150 mS/cm.

How to Convert Siemens per Metre to Millisiemens per Centimetre
- 1 S/m = 10 mS/cm
- 1 mS/cm = 0.1 S/m
- Example: convert 15 S/m to mS/cm: 15 S/m = 15 × 10 mS/cm = 150 mS/cm
Formula
mS/cm = S/m × 10
Derivation from SI units:
- The SI unit of electrical conductivity σ = 1/ρ
- 1 mS/cm = 0.1 S/m = 1000 µS/cm
Both units are defined exactly, so the factor is exact. Siemens per Metre definition: siemens per metre; Millisiemens per Centimetre definition: millisiemens per centimetre.
Worked examples
- A reading of 0.5 S/m converts to 5 mS/cm.
0.5 S/m × 10 = 5 mS/cm - A value of 1000000 S/m is 10000000 mS/cm.
1000000 S/m × 10 = 10000000 mS/cm
