How to Convert Tds to Conductivity
- 1). Determine the conversion factor needed to convert TDS to conductivity. The conversion factor will depend on the types of minerals and salts dissolved in the water. This conversion factor can be found in published tables. If the actual conversion factor cannot be found, then 0.67 is frequently used as an approximate conversion factor.
- 2). Use a TDS meter to measure the TDS of your water or solution. Turn the TDS meter on and stick the probe into the solution. Record the TDS reading.
- 3). Divide the TDS by the conversion factor. This will give you the conductivity of the solution.
Conductivity = TDS/Conversion Factor
