13.2 Appendix 2: How to calculate the TDS conversion factor 

To determine the TDS conversion factor, use the following formula: 
 
 
Factor= 
 
 
 

Where: 

Actual TDS: value of a precisely weighed quantity of anhydrous NaCl or KCl dissolved in high 
purity water. 
Actual Conductivity: the meter measured conductivity value. 
 
For example: 
Dissolve 64 grams of potassium chloride reagent in 1L distilled water. If its conductivity value is 
100mS/cm, then TDS conversion factor is 0.64.
