202039 So this is basically “parts per part,” meaning that for one part solution you have 0.0002 parts salt. But of course, having this many decimal points isn’t exactly convenient, so to convert to PPM you multiply by 1,000,000 = 10 6, giving: 0.0002 × 10 6 = 220 PPM. The general approach works for volume calculations, too.احصل على السعر
