Let us try this again: >The units for conductivity are mhos (inverse ohms) = Siemens. > >The units for resistivity are ohms. Conductance = 1 / Resistance or X mhos = 1 / Y ohms > (Conductance) (Resistance) Then 1micromho = 1 X 10^-6 = 1 / 1 X 10^6 (1 Megohm) which does not = 1 megohm. Also, 20 micromhos = 1 / 50 kohms 1 micromho can not = 1 megohm and 20 micromhos can not = 50,000 ohms or they would be both a measure of either conductivity or resistance. Where they are really inverses of each other a conductivity of 20 micromhos is derived from a resistivity of 50,000 ohms.
