CO2 Gas Concentration Defined |

Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 of them would be of carbon dioxide and 999,000 molecules would be some other gases. When you start counting over 10,000ppm, most scientists and manufacturers change from ppm to percent concentration. So instead of describing a …

PPM mg/m3 converter for gases - Teesing

Concentrations of chemicals in the air are usually measured as the mass of chemicals (milligrams, micrograms, nanograms or picograms) per volume of air (cubic meters or cubic feet). Concentrations can also be expressed as parts per million (ppm) or parts per billion (ppb) by using a conversion factor. This conversion factor is based on the molecular weight of the chemical and it is different ...
