A siemen is a measure of conductivity. It is the reciprocal of resistance. us/cm is neither, it is conductivity per cm.
18.2 megohms is 1/18.2X10^6 siemens =~ .055 microsiemens Marshall RodStevenson wrote: > Grant thanks for the reply, but now I'm a little confused.I thought > that ms/cm was the unit of resistance, not it's reciprocal and that > Mw (Megohms) was the unit of conductance?
