13 Jul 2014 The annual average concentration of carbon dioxide (CO2) in the atmosphere stood at 395.3 parts per million (ppm) in 2013—a 27 percent 

Just as per cent means out of a hundred, parts per million means out of a million which is represented as 1/1000000. PPM is a dimensionless quantity used to measure the concentration of a substance in a solution. One ppm is equivalent to 1 milligram of a substance per liter of water (mg/l) or per kilogram of soil (mg/kg).

Just as PER cent means out of a hundred, so parts PER million or ppm means out of a million. Usually describes the concentration of something in water or soil.

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. Parts per million (ppm) is how many parts a certain molecule or compound makes up within the one million parts of the whole solution. It's typically used to describe concentrations of chemicals Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc. Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution.
