Millisiemens per Centimetre (mS/cm)
The millisiemens per centimetre is 0.1 S/m. Conductivity meters use it for brackish water, seawater (about 50 mS/cm) and calibration standards such as 12.88 mS/cm.
Symbol: mS/cm
Quantity: electrical conductivity
SI relation: 1 mS/cm = 0.1 S/m (exact)
Derivation: 1 mS/cm = 0.1 S/m = 1000 µS/cm
Exact: yes, by definition
Same quantity as decisiemens per metre (dS/m) : the factor between them is exactly 1.
Typical uses
- Seawater and brackish water
- Conductivity meter calibration standards
- Hydroponics and fertiliser solutions
