mg/m3: milligrams of contaminant per cubit meter. Usually it is referenced at a pressure of 1atm and 25ºC. Air pollutant concentrations, as measured or as calculated by air pollution dispersion modeling, must often be converted or corrected to be expressed as required by the regulations issued by various governmental agencies. Regulations that define and limit the concentration of pollutants in the ambient air or in gaseous emissions to the ambient air are issued by various national and state (or The SI unit of volume is the cubic meter (m3).

Definition: Formula: concentration (ppm) = 24.45 x concentration (mg/m 3) ÷ molecular weight For example: 50 mg/m 3 of NH 3 (17.03 g/mol) 24.45 x 100 ppm / 17.03 = 71.785ppm In relation to the base unit of [density] => (kilograms per cubic meter), 1 Grams Per Cubic Meter (g/m3) is equal to 0.001 kilograms-per-cubic-meter, while 1 Parts Per Million (ppm) = 0.001 kilograms-per-cubic-meter. 1 Grams Per Cubic Meter. So each ppm of methane will contribute about 16 / 1,000,000 g to each 22.4L of the gas mixture. Or (adjusting for the volume conversion to cubic metres which contain 1,000 L) 44.7 * 16 /1,000,000 g/cubic metre.

STEL: 20 ppm. STEL: 59 mg/m3 5 g/kg. > 5 g/kg ( Rat ).

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).
