mr. green thumb 01 New Member. just measured the ppm of rain water and it is 3-5 which is the same as reverse osmosis. Most tap water is 200-350 ppm which is not good for growing. So if you want good water cheap...catch is outta your gutters. plants will love it! Oct 16, 2010. #1.
Parts per million (ppm) is a unit of measurement for very low concentrations by mass (or weight) of one substance dissolved in another substance, called the solvent. Strictly speaking, you canât convert ppm to micrograms per cubic meter, since a cubic meter is a measure of volume, not mass. microgram is one-millionth of a gram. Thus, a concentration of one ppm means there is one microgram of a substance per gram of solvent. Find the mass of the solvent contained in one cubic meter. To do this, look up the specific gravity of the solvent.
