Microsiemens per Centimetre (µS/cm)
The microsiemens per centimetre is 10⁻⁴ S/m, the standard unit for water quality: ultrapure water is about 0.055 µS/cm, drinking water typically 50–800 µS/cm.
Symbol: µS/cm (ASCII: uS/cm)
Quantity: electrical conductivity
SI relation: 1 µS/cm = 0.0001 S/m (exact)
Derivation: 1 µS/cm = 10⁻⁴ S/m = 0.001 mS/cm
Exact: yes, by definition
Typical uses
- Drinking, boiler and cooling water quality
- Purified water in pharmaceuticals
- Conductivity meters and the 1413 µS/cm calibration standard
