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. WebOne part per million (by volume) is equal to a volume of a given gas mixed in a million volumes of air: A micro liter volume of gas in one liter of air would therefore be equal to 1 ppm: Today's more and more there is an interest to express gas concentrations in metric units, i.e. µ g/m 3.

WebApr 15, 2024 · There is a very subtle difference in using nmol/mol vs. ug/kg. The typical definition of ppb is ug X in a kg of solution not the solvent. 100 ppb NaCl in water mean 100 ug NaCl "in" 1 liter of water solution. The total volume is 1 L. The analyte is a part of the solvent weight. With 100 ppm NaCl as 100 nmol NaCl dissolved in 1 mol water.
