PPM can be converted to EC by dividing by 500. To convert from siemens to Ohms is s=1/ohms, you can also go the other way and do ohm=1/s for siemens to ohms. EC Values for Hydroponics and Soil by Week Measure the pH level If you choose to measure by PPM, hydro growers should begin with a solution that has 500 PPM and increase by 50 every week. The pH should be close to 5.5, and at least 5.2.

EC 1.0 ms/cm = 500 ppm (USA Hanna) 1000 us/cm = 500 ppm Conversion factor = ppm / (ms/cm * 1000).50 = 500ppm / (1000us/cm) ] The answer is your meter's convertion factor and should be a number between 0.50 and 0.72 To improve accuracy, take ec and ppm readings from your res daily for about ten days.
