Density of the Solution (ρ) =   kg/m3  (g/L)


Note 1:

Parts per million (ppm) is a dimensionless notation and, therefore, can only be used as a unit of measure of concentration, equivalent to mg/L, in aqueous solution of low concentration, with density equal to that of water (1000 kg/m3), since in this case one liter of solution has a mass equal to 1000 grams, being 1 mg/L = 1 mg/1000 g = 1 g/1000000 g = 1 ppm. For conversion of ppm to mass/volume concentration units, in solutions with different densities from 1000 kg/m3, fill the calculator field with the solution density value. For more information, see article from Wikipedia.
