EC Measurement in Soil. Electrical conductivity (EC) is the ability of a material. to transmit (conduct) an electrical current and is com-. monly expressed in units of milliSiemens per meter. (mS/m). Soil EC measurements may also be reported in. units of deciSiemens per meter (dS/m), which is equal to. the reading in mS/m divided by 100.
