About Microsiemens per metre
The microsiemens per metre (µS/m) equals 10⁻⁶ S/m, the scale for freshwater lakes and rivers (100-2 000 µS/m) and weakly mineralised groundwater. It is the SI-coherent companion to the more commonly measured µS/cm: divide a µS/cm reading by 100 to obtain µS/m. 1 µS/m = 10⁻⁶ S/m = 0.01 µS/cm.
About Millisiemens per metre
The millisiemens per metre (mS/m) equals 10⁻³ S/m and is the preferred unit in geophysical electromagnetic induction surveys (EM-31, EM-38) for soil and shallow-subsurface conductivity mapping. Agricultural soil reads 5-200 mS/m; saline soils exceed 400 mS/m; near-surface marine sediments reach 1 000 mS/m. 1 mS/m = 10⁻³ S/m = 10 µS/cm.
