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

How to Convert Millisiemens per Metre to Microsiemens per Centimetre
- 1 mS/m = 10 µS/cm
- 1 µS/cm = 0.1 mS/m
- Example: convert 15 mS/m to µS/cm: 15 mS/m = 15 × 10 µS/cm = 150 µS/cm
Formula
µS/cm = mS/m × 10
Derivation from SI units:
- 1 mS/m = 10⁻³ S/m = 10 µS/cm
- 1 µS/cm = 10⁻⁴ S/m = 0.001 mS/cm
- 1 mS/m = 0.001 S/m ÷ 0.0001 S/m per µS/cm = 10 µS/cm
Both units are defined exactly, so the factor is exact. Millisiemens per Metre definition: millisiemens per metre; Microsiemens per Centimetre definition: microsiemens per centimetre.
Worked examples
- A reading of 10 mS/m converts to 100 µS/cm.
10 mS/m × 10 = 100 µS/cm - A value of 100 mS/m is 1000 µS/cm.
100 mS/m × 10 = 1000 µS/cm
