Hi George, The theoretical relationship between conductivity and ppm as silver ions (at 10ppm) is 1ppm = 0.57uS or 1uS = 1.75ppm.
However, in practice it has been found that a 1:1 relationship (uS to ppm) through to 1:1.2 seems to be about right. Trem might be able to elaborate a little here.

A recent posting said that some time ago you did some research about quantifying the reading to an approximation of ppm. The person posting said he recalled that you came up with a number -- .59 -- with which to multiply the PWT reading. I have searched the archives, but have not been able to find your original post on the matter. Could you please confirm the .59 figure? Not the science, just the arithmetic.
