    https://www.chemteam.info/Solutions/ppm1.html

    WEBThe expression "1 ppm" means a given solute exists at a concentration of one part per million parts of the solution. These are two common ways to think about what the concentration "1 ppm" means: a) it is one-millionth of a gram per gram of sample solution. b) it is one gram of solute per million grams of sample solution.

    WEBIn science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement.
