Given: At normal temperature and pressure, the following conversion formulas may be used to convert back and forth between ppm and mg/m3 . mg/m3= [(MW x ppm) / 24.45] or ppm = [(24.45 x mg/m3 ) / MW] MW: molecular weight in g/mole In these equations 24.45 is the volume (in liters) of a mole (gram molecular weight) of a gas or vapor when the pressure is at 1 atmosphere (760 mmHg) and the temperature is at 25°C. When temperature...
