PPM & Minerals (Hard vs. Soft Water) This is a catchall term that simply means “parts per million.” it is used to calculate the quantity of a contaminant dissolved in air or water. Even chlorine and chloramine levels are calculated and represented using PPM.

Wagner et al . ([1][1]) present a high-resolution record of leaf stomatal index (SI), from which they reconstruct the concentration of atmospheric CO2 in the early Holocene (10,070 to 9,38014C-yr BP, 11,300 to 10,600 cal yr BP) ([1][1], [2][2]). The resulting record shows a CO2 concentration of about 270 ppmv at 11,300 yr BP, a sharp increase to about 330 ppmv at 11,260 yr BP, and (with the

While (Mg/l) is represented as the ratio of mass of the substance per volume in the concentration, parts per million is represented as the ratio of mass per million grams in the concentration. Use this online converter to convert PPM to Mg/L.
