PPM, which could be either PPM (wt) or PPM (vol), or g/m3, which does not specify whether the gas is at actual or standard condition (which makes a big difference in case of sales gas). Originally, I was told that: ppm (wt) x 1000x Density = mg/m3, and ppm (vol)x1000 = mg/m3 ppm↔ml/m3 1 ppm = 1 ml/m3 ppm↔ml/l 1 ml/l = 1000 ppm ppm↔ul/m3 1 ppm = 1000 ul/m3 ppm↔ug/mg 1 ug/mg = 1000 ppm ppm↔g/ton 1 ppm = 1 g/ton » Milliliter/m3 Conversions: ml/m3↔per 1 per = 10000 ml/m3 ml/m3↔ppm 1 ml/m3 = 1 ppm ml/m3↔ppb 1 ml/m3 = 1000 ppb ml/m3↔ppt 1 ml/m3 = 1000000 ppt ml/m3↔ppq 1 ml/m3 = 1000000000 ppq ml/m3↔g/kg 1 g/kg = 1000 ml/m3 ml/m3↔ug/g 1 ml/m3 = 1 ug/g ml/m3↔ng/ug 1 ng/ug = 1000 ml/m3 betyder att måttet är volymsbaserat.

ppm: 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 microgram per liter (ug/L), which is about 1 ppb. Concentrations in Air Concentrations of chemicals in air are typically measured The unit eq (a keq is 1000 eq) refers to molar equivalent of potential acidity resulting from e.g. sulphur, oxidised and reduced nitrogen, as well as base cations. For example: 1 keq S ha -1 yr -1 is equal to 16 kg S ha -1 yr -1. When converting acidifying compounds the valency is important and is connected with the charge on the ion. To convert mg/m 3 to ppm at other temperatures and pressures, one must calculate the volume of 1 gram molecular weight of an airborne contaminant (e.g.

Löslighet i vatten: Sättet att beräkna ozon dos (g/m3) idag är inte optimalt i polerings syfte. Om syftet är att måste man arbeta med löst ozonkoncentration i ppm eller ppb för att få. STEL: 1500 mg/m3. -.

6 Sep 2015 Converting Atmospheric Pollutant Concentrations: from ppmv to mg/m3. First, ppm (parts per million ) and ppb (parts per billion) are defined as

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.

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. By this formula, a cubic metre of pure methane would weigh ~715g at STP so you could just work with that by multiplying by the ppm value. For these conditions, the equation to convert from concentration in parts per million (ppm) to concentration in milligrams per cubic meter (mg/m3) is as follows: Concentration (mg/m3) = 0.0409 x concentration (ppm) x. molecular weight.

1 L จาก Pb( Volume mixing ratio: usually ppm - parts per million (10-6); or ppb - parts per to a different air concentration in µg m-3 depending on the ratio of NO to NO2. สามารถเปลี่ยนหน่วยจาก ppm เป็น mg /L ได้เลย. - โดย 1 ppm = 1 mg /L = 1 g/m3 = 1 mg/kg. การเปลี่ยนหน่วย พีพีเอ็ม (ppm) เป็น มิลลิกรัม/ลูกบาศก์เมตร (mg/m3) ในอากาศ. g/mole. = grams per mole.
