Conversion ppm mg/m3

Concentrations of chemicals in the air are usually measured as the mass of chemicals milligrams, micrograms, nanograms or picograms per volume of air cubic meters or cubic feet. Concentrations can also be expressed as parts per million ppm or parts per billion ppb by using a conversion factor. This conversion factor is based on the molecular weight of the chemical and it is different conversion ppm mg/m3 every chemical.

The unit ppm is used in several branches in different ways. The use of ppm therefore has to be specified in the input fields below, in the way it should convert the value with the proper unit. For more theory about the use of ppm, please see the documentation below. In the input field of Molecular Weight you could either choose from the drop-down list, or you could fill in the value of the molecular weight of the gas. If the molecular weight is unknown to you, please try our Molecular Weight Calculator. The significance is automatically determined. Use extra zero's to expand the significance.

Up to eight digits, including digits after the decimal point, can be entered in input fields. Enter the concentration values and select the concentration unit from the pull-down list. Either directly enter the name of the gas, or select it from the pull-down list. Alternatively, directly enter the molecular weight. If the pressure is not one atmospheric pressure hPa , enter the pressure in the corresponding field. Home Technical Information Concentration unit conversion Concentration unit conversion.

Concentrations of chemicals in the air are usually measured as the mass of chemicals milligrams, micrograms, nanograms or picograms per volume of air cubic meters or cubic feet. Concentrations can also be expressed as parts per million ppm or parts per billion ppb by using a conversion factor. This conversion factor is based on the molecular weight of the chemical and it is different for every chemical. The temperature of the atmosphere also has an influence on the calculation.

Conversion ppm mg/m3

The calculator below converts between volume concentration of gas, i. A detailed description of the calculation can be found under the calculator. As mentioned above, the volume concentration of gas is defined as the ratio of the gas volume to the total volume. Ppm is often used for low concentration values, typical for air pollution. The conversion from one unit to another is based on the Law of Avogadro's , according to which equal volumes of gases, at the same temperature and pressure, contain the same number of molecules. According to the first corollary from Avogadro's law, one mole of any gas under the same - isobaric and isothermal - conditions occupies the same volume. Knowing ppm, we can find how many liters of gas are contained in one cubic meter of total volume.

Privacy Policy. Point of use purifiers. Uncheck if you are answering for madur question. In air pollution literature ppm applied to a gas, always means parts per million by volume or by mole. Copyright madur all rights reserved. International prototype of the kilogram, www. The volume V divided by the number of molecules n represents the molar volume V n of the gas with a temperature T and pressure P. These are identical for an ideal gas, and practically identical for most gases of air pollution interest at 1 atm. This can be made clear by the following notation:. Micro-bulk purifiers. Even the concerning concentration of gas dissolved in the water is affecting the density of the solution.

These are used in air quality thresholds and air quality indexes to help provide a baseline for what constitutes as clean air and for people to understand the acceptable level of pollutants in the air they breathe. But what do these measurement units stand for, exactly?

TeamViewer remote support software. By checking the dimensions of the most right part of the equation, there will be found a dimensionless value, like the concentration in ppm is. Concentrations of chemicals in the air are usually measured as the mass of chemicals milligrams, micrograms, nanograms or picograms per volume of air cubic meters or cubic feet.
