Parts per Million (ppm) is the commonly used unit for the measurement of small levels of pollutants called total dissolved solids (TDS) in air, water, body fluids, etc. Microsiemens (Î¼S) is the unit of measurement of electrical conductivity (EC) in water or other liquids. Use this online unit conversion calculator to convert Parts Per Million (PPM) to Microsiemens (Î¼S). Enter the value to be converted in the PPM field and tap the calculate button to known the Î¼S conversion.
1 PPM is equal to 1.56 microS/cm.
Hence 12 parts per million is equal to = 1.56 x 12 microS/cm
Microsiemens (Î¼S) = 18.72 microS/cm
