Since there are 1000 g in one liter of water, converting to mg would result in 1,000,000 mg per liter of water or ppm. For instance, chlorinated water will show a positive ORP value whereas sodium sulfite (a reducing agent) loses electrons and will show a negative ORP value. The system worked well with TDS of less than 50,000 ppm. 0-5-10 = 829 ppm 0-8-16 = 1326 ppm Addback Calculator - (For Advanced Users) Say you were running the 0-8-16 formula, at 0. For example, to convert 150 ppm calcium as CaCO 3 to epm (Table 40-1) divide by 50 (the equivalent weight of calcium carbonate) and obtain 3.
