Beteckningar ppm omräknas från mikrogram/m3 (g/m3) enligt for- meln: ppm = 24,1 Röd lysdiod lyser - CO2-koncentration 1201 ppm och högre.
How can ppm be converted to µg/m 3 ? 1 gram of SO2 for every million grams of air (parts per million by mass);; 1 mL of Write "ppm" in terms of cubic meters.
mg/m3: milligrams of contaminant per cubit meter. Usually it is referenced at a pressure of 1atm and 25ºC. Air pollutant concentrations, as measured or as calculated by air pollution dispersion modeling, must often be converted or corrected to be expressed as required by the regulations issued by various governmental agencies.
Mass concentration representation: the mass per ton of air contained in the air mg / m3 volume concentration represents: one million volumes of air contained in the volume of pollutants, that is, concentration results of most of the gas detection equipment is volume concentration (ppm).

The SI unit of volume is the cubic meter (m3). Suppose a constituent of a gaseous mixture is at a concentration of 1 ppm. If one were to separate the mixture into its components, and measure the volume of each component, there would be 1 m3of the gas of interest for every 106 m3of the mixture. 1 m3constituent/106 m3of the mixture = 1 ppm
