x (%) = 500ppm / 10000 = 0.05%. Also, use P ercent to PPM Calculator for more conversion. Convert Parts Per Million to Tons [metric] Per Cubic Kilometer (ppm in t/km3 [metric]). Parts Per Million and Tons [metric] Per Cubic Kilometer both are the units of DENSITY. EC = Electrical Conductivity TDS (ppm)= EC (dS/m) X 640, for EC between 0.1 and 5.0 dS/m 690ppm / 640 = 1 08 dS/m (EC)690ppm / 640 = 1.08 dS/m (EC) 1.08 dS/m X 640 = 690 ppm or TDS TDS (ppm) = EC (dS/m) X 800, for EC > 5.0 dS/m 690ppm / 800 = 0.86 dS/m (( )EC) 0.86 dS/m X 800 = 690 ppm 0.86 dS/m X 800 = 690 ppm of of TDSTDS Percent to ppm converter How to convert ppm to percent.

1.0 EC = approx. 600 ppm as a rule of thumb. So, .333 EC = 200 ppm and .50 EC = 300 ppm, etc. The 0.00 - 20.00 EC scale just means your meter is capable of reading up to 20.00 EC - it's unlikely you would ever go much above 2.0 EC (1200 ppm).

Most inexpensive meters will only display PPM and usually in the 500 scale.
