I'm trying to get an idea of the OHMS of resistance to millisiemens.

From googeling

.001 millisiemens per centimeter = 1 EC

200 millisiemens = 5 OHMS

so 1 ohm would be 40 millisiemens

40 millisiemens / .001 would be 40,000 OHMS

I don't think that's right or a standard ohm meter could measure EC of a fluid.

So need some help understanding this.
