c) För att beräkna volym måste man också känna till gasens volym per mol. För ideal gas anser man att gasen upptar 22,4 lit/mol. Genom att dividera molvikten 46 g/mol med gasens volym 22,4 lit/mol erhålls en faktor 2,05 som, om ingångsvärdet är ppm, direkt ger sorten g/dm3 eller mg/m3. The conversion from mg/Nm3 to ppm is done according the following formula: (mg/Nm3) * (22.4/MW) = ppm where MW is the molecular weight of the gas. 1 ppm = 1µl/l = 1 mg/kg Đơn vị khác. Ngoài ppm còn có các đơn vị về lượng khác cũng được dùng như: ppb (một phần tỷ, 10 –9), ppt (một phần nghìn tỷ, 10 −12) và ppq (một phần triệu tỷ, 10 −15).

The OSHA permissible exposure limits (PELs), as found in Tables Z-1, Z-2, and Z-3 of the OSHA General Industry Air Contaminants Standard (29 CFR 1910.1000), that were effective on July 1, 1993* and which are currently enforced by OSHA are listed on the page for each chemical in the Pocket Guide. How to convert Parts Per Million to Grams Per Cubic Meter (ppm to g/m3)? 1 ppm = 1 g/m3. 1 x 1 g/m3 = 1 Grams Per Cubic Meter.

Always check the results; Concentrations of gaseous pollutants is sometimes given in units of mass per volume, and at other times in ppb or ppm. ppb (v) is parts per billion by volume ( i.e., Fill in either the “ppm” value (X) or the “mg/m3” value (Y) AND the molecular weight of the compound.
