There are a million cubic centimeters in a cubic meter (1 cm3 = (10-2)3 m3 = 10-6 m3) so one part per million of SO2 by volume in air is actually 1 cm3 SO2/ 1 m3 of air. Convert cm3 of SO2 gas to Âµg SO2.You'll need the density of the gas at the appropriate temperature and pressure. 1 gram of SO 2 for every million grams of air (parts per million by mass); 2  1 mL of SO 2 for every million mL of air (parts per million by volume); 3  1 gram of SO 2 for every million mL of air (parts per million by mass per volume). 4  Write ppm in terms of cubic meters.
