WQM: Conductivity to Salinity Conversion



  1. Collect conductivity (uS/cm) and water temperature (C) data.
  2. Use spreadsheet or calculator to convert conductivity and temperature data to salinity value.
  3. Equations used are based on the practical salinity scale and are valid for surface waters with salinity between 2 and 42 ppt. Please view the source to this document and consult Standard Methods for the Examination of Water and Wastewater if you have questions or concerns.
