EC or Electrical Conductivity is a standard universal measure, Yet PPM is not. Different parts of the world convert EC to PPM differently. You as a grower will need to learn your countries conversion so you are able to keep accurate records.

USA (NA) : 1ms/cm (EC 1.0) = 500 ppm

European : 1ms/cm (EC 1.0) = 640 ppm

Australian : 1 ms/cm (EC 1.0) = 700 PPM
