What is ppm? 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 = 0.000001 = 1×10 -6. One ppm is equal to 0.0001%:
