Total Dissolved Solids, (,TDS,) ,TDS, is a measure of all of the dissolved substances in water. ,TDS, and conductivity levels in water are typically closely correlated and a conversion factor of approximately 640 is often used to predict ,TDS, from conductivity which is easier to measure. The formula is ,TDS, (mg/L) = 640 * EC (mmhos/cm).
