Conductivity to TDS comversion
Just to clarify for anyone that may be digging around through old posts looking for information...

Micromhos or Microsiemens is a unit of measure for Conductivity.
The relationship between conductivity and TDS is non-linear and no single multiplier can be used to convert between the two. TDS is dependent on the type of mineral and does not only refer to calcium carbonate.
You can take a look at this article to see what I mean: Conductivity to TDS conversion
Different minerals have a different conductance value.
Again, just to clarify...
