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. mg/m3↔oz/yd3 1 oz/yd3 = 37079.776318842 mg/m3 mg/m3↔ton/yd3 1 ton/yd3 = 1307873397.8551 mg/m3 mg/m3↔lbs/in3 1 lbs/in3 = 27679904702.91 mg/m3 mg/m3↔per 1 per = 10000000 mg/m3 mg/m3↔ppm 1 ppm = 1000 mg/m3 mg/m3↔ppb 1 mg/m3 = 1 ppb mg/m3↔ppt 1 mg/m3 = 1000000 ppt mg/m3↔slug/ft3 1 slug/ft3 = 515378818.52553 mg/m3 This is the same as grams per 1,000 liters, which may be converted to milligrams per liter (mg/L). Therefore, 1 g/m3 = 1 mg/L = 1 ppm. Likewise, one milligram per cubic meter (mg/m3)is the same concentration in water as one per liter (ug/L), which is about 1 ppb. Read Also: How to convert ppm to mg/m3 (Use NIOSH Calculator) Occupational exposure limits (OELs, TLVs, PELs, etc.) can be expressed in parts per million (ppm) only if the substance exists as a gas or vapour at normal room temperature and pressure.

Because the temperature is higher, and the pressure lower, the actual cubic meter of gas analyzed is larger than it would be at "normal" conditions. 1 m³ x 273.15 K/393.15 K x 1000 mb/1013.25 mb = 0.686 Nm³. So your reading of 2100 mg/m³ is 2100 mg/0.686 nm³ = 2917 mg/Nm³. ppm to percent converter How to convert percent to ppm. 1% = 10000ppm.

Re: Different between Nm3/h = m3/h ? The difference between Nm3/h and m3/h for compressor is very important because the first one correspond to standard conditions (1 bar and 20°C), where the density of the air is 1.2060 kg/m3. m3/h usually correspond to the flow at pressure conditions (7 bar and 60°C), where the density of the air is 8.3934 kg/m3.
