About Siemens per centimetre

The siemens per centimetre (S/cm) equals 100 S/m and is used in analytical chemistry where measurements are performed in centimetre-scale conductivity cells. Concentrated KCl solutions (≈1.29 S/cm at 25 °C) serve as primary calibration standards; concentrated H₂SO₄ ≈1 S/cm; liquid mercury ≈1 000 S/cm. Equivalent conductance in electrochemistry is traditionally tabulated in S·cm²/mol. 1 S/cm = 100 S/m.

About Millisiemens per centimetre

The millisiemens per centimetre (mS/cm) equals 0.1 S/m, the practical scale for seawater (≈50 mS/cm), blood plasma (≈14 mS/cm), and standard electrolyte solutions in electrochemistry laboratories. Conductivity-cell instruments for desalination plants and industrial process control commonly read in mS/cm; NIST-traceable calibration solutions are certified in mS/cm. 1 mS/cm = 100 mS/m = 0.1 S/m.
