With the help of his tool, gaseous pollutants can be converted from mg/Nm³ into ppm or from ppm into mg/Nm³. For the conversion to ppm, please insert the measurement in mg/Nm³. For the opposite conversion please insert the measurement in ppm. Please insert only the ppm or the mg/Nm³ value into the converter.
Because most official pollution levels also require the oxygen reference value, the calculation also takes into consideration the O2-reference value for flue gases. For oxygen correction calculations, the fields for measured O2-value and the desired reference value also need to be filled in.
