| microsiemens per centimetre to siemens per centimetre | 0.000001 S/cm |
| microsiemens per centimetre to millisiemens per centimetre | 0.001 mS/cm |
| microsiemens per centimetre (µS/cm) | 1 µS/cm |
| microsiemens per centimetre to decisiemens per metre | 0.001 dS/m |
| microsiemens per centimetre to millisiemens per metre | 0.1 mS/m |
Convert between S/m, MS/m, S/cm, mS/cm, µS/cm, dS/m, mS/m and %IACS. %IACS compares a metal with the International Annealed Copper Standard, exactly 58 MS/m, so 1 %IACS = 0.58 MS/m.
Water conductivity units
Water quality is usually given in µS/cm (pure and drinking water) or mS/cm (seawater, brines). 1 mS/cm = 1000 µS/cm = 1 dS/m. Readings are normally temperature-compensated to 25 °C.
Electrical Conductivity unit definitions
- siemens per metre (S/m)
- The siemens per metre is the SI unit of conductivity (σ), the reciprocal of resistivity: σ = 1/ρ. Copper is about 5.8 × 10⁷ S/m; seawater about 5 S/m.
- percent IACS (%IACS)
- Percent IACS expresses conductivity relative to the International Annealed Copper Standard, a reference copper of exactly 58 MS/m at 20 °C. Pure annealed copper is about 100–103 %IACS; aluminium about 61 %IACS. Reference: 100 %IACS = 58 MS/m at 20 °C (International Annealed Copper Standard)
- 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.
- 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.
- megasiemens per metre (MS/m)
- The megasiemens per metre is 10⁶ S/m, numerically equal to m/(Ω·mm²). Metal conductivities are usually quoted in MS/m: copper 58–59.6, aluminium about 35–37.7 MS/m.
- decisiemens per metre (dS/m)
- The decisiemens per metre is 0.1 S/m, numerically equal to mS/cm. Soil and irrigation-water salinity (EC) is usually reported in dS/m.

- siemens per centimetre (S/cm)
- The siemens per centimetre is 100 S/m, common for electrolytes, ionic conductors and conductive polymers.
- millisiemens per metre (mS/m)
- The millisiemens per metre is 10⁻³ S/m. Drinking-water regulations in some countries quote conductivity in mS/m.
