For smaller volumes, sensor manufacturers and the gas industry measure CO2 and other trace gases in parts per million. For example, % CO2 is equal to 400 parts per million, which is commonly abbreviated as "400 ppm". Indoor Air Quality 10,000ppm CO2. When talking about indoor air, partspermillion makes sense. Only in rare instances like ...

For example, 413 parts per million of CO 2 (abbreviated as ppm) means that in every million molecules of (dry) air there are on average 413 CO 2 molecules. The table below gives approximate values of gases in the atmosphere for 413 ppm of CO 2 in dry air (this is roughly the average amount of CO 2 in the atmosphere in the middle of the year 2020). All species have been expressed as ppm ...
