Which formulas are used to convert gas concentration in ppm into mg/m3 and other units?
Basic formulas for conversion of ppm concentration are as follows:
ppm × molecular weight / 24,450 = mg / L
ppm × molecular weight / 0.02445 = μg / m3
ppm × molecular weight / 24.45 = mg / m3
ppm × molecular weight × 28.3 / 24,450 = mg / ft3
