I think it is necessary to know the uS of the distilled water you start
with, before you can say uS can be considered the same as ppm.
But if the distilled water (tested with a Hanna PWT which I think is an
EC meter) reads, as an example, .3 uS then I consider uS and ppm the
same. The difference is too small to be concerned about. If you have a
TDS meter, then I don't know, it reads to a different scale and will not
read below 1.0, which is not pure enough distilled water for me to get
clear CS.

Which had me think was my 15us brew a 7/8 ppm or 15. The variance is
large and given the discussions of high ppm recently it got me even
more interested.
