5 Apr 2021 CO2 concentration at the Mauna Loa Observatory reached a daily record of 421.21 Parts Per Million (PPM) on April 3. This is the first time in the

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).

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.
