ppm: partsper million

ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000. ppm is dimensionless quantity, a ratio of 2 quantities of the same unit. For example: mg/kg. One ppm is equal to 1/1000000 of the whole: 1ppm = 1/1000000 = = 1×106 . One ppm is equal to %: 1ppm = %. ppmw


ppm: partsper million

One ppm is equal to %: 1ppm = %. ppmw. ppmw is an abbreviation of parts per million weight, a subunit of ppm that is used for part of weights like milligrams per kilogram (mg/kg). ppmv. ppmv is an abbreviation of parts per million volume, a subunit of ppm that is used for part of volumes like milliliters per cubic meter (ml/m 3).
