I was wondering if anyone can help clarify the relation between GH, KH and conductivity.

I know that 33ms = 1GH = 17.9 ppm.

In my case, I have 17 GH and 12 KH, thus a great need for some serious RO.

The question is: What is my conductivity?? ???
Is it: 17 x 33 = 561ms?

Or, does Kh also contribute to conductivity? :-[
If so, is my conductivity this:
(17+12) x 33 = 957ms?

I have a hunch that the conductivity is even higher than 957 ms, that Gh and Kh both contribute but still do not encompass conductivity. I really have no idea, and I'd love to know.

KH is only the buffer for acid affecting the ph. KH is not added into the hardness equation. KH is the amount of "carbonates " in the water.


Yes if your Gh is 17 it is very hard and probably about 531 ms GH Is a measure of minerals in the water mainly calcium and magnesium.

Thanks Ardan!

Well, I work at a pool so I tested my conductivity there and it was 922ms. But who knows about the accuracy. Either way I have liquid rock.
