Convert Millisiemens per Centimetre to Siemens per Metre
1 millisiemens per centimetre (mS/cm) = 0.1 siemens per metre (S/m). 1 S/m = 10 mS/cm. Example: 15 mS/cm = 15 × 0.1 = 1.5 S/m.

How to Convert Millisiemens per Centimetre to Siemens per Metre
- 1 mS/cm = 0.1 S/m
- 1 S/m = 10 mS/cm
- Example: convert 15 mS/cm to S/m: 15 mS/cm = 15 × 0.1 S/m = 1.5 S/m
Formula
S/m = mS/cm ÷ 10
Derivation from SI units:
- 1 mS/cm = 0.1 S/m = 1000 µS/cm
- The SI unit of electrical conductivity σ = 1/ρ
Both units are defined exactly, so the factor is exact. Millisiemens per Centimetre definition: millisiemens per centimetre; Siemens per Metre definition: siemens per metre.
Worked examples
- A reading of 1 mS/cm converts to 0.1 S/m.
1 mS/cm × 0.1 = 0.1 S/m - A value of 5 mS/cm is 0.5 S/m.
5 mS/cm × 0.1 = 0.5 S/m

Frequently asked questions
How many siemens per metre are in 1 millisiemens per centimetre?
1 mS/cm = 0.1 S/m.
How do I convert millisiemens per centimetre to siemens per metre?
Multiply the value in mS/cm by 0.1, or divide it by 10. For example, 15 mS/cm × 0.1 = 1.5 S/m.
Is the mS/cm to S/m conversion exact?
Yes. Both units are defined exactly, and 1 mS/cm is exactly 0.1 S/m.
