Conversion ppm mg/m3

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, conversion ppm mg/m3, or you could fill in the value conversion ppm mg/m3 the molecular weight of the gas.

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.

The density of gas can be calculated by the Law of Avogadro's, which says: equal volumes of gases, at the same temperature and pressure, contain the same number of molecules. Another way of expressing this value is ppmv, conversion ppm mg/m3.

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.

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. By dividing this number by the molar volume of the gas for a given temperature and pressure , we can get the number of moles of gas in one cubic meter of total volume.

To express this concentration with metric units the density of water is needed. Today's more and more there is an interest to express gas concentrations in metric units, i. Point of use purifiers. Show all. 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.

A conversion factor based on the molecular weight, the temperature and pressure where the measurement is taken is used, so every measurement taken will have a slightly different conversion factor. Back to all White Paper Articles.

By nature there's a chance that water contains a certain concentration of Deuterium which influences the density of the water. Molecular weight. Quick Support Online support. Accurate calculations on these conversions are only possible when the density of the water is measured. Enter the concentration values and select the concentration unit from the pull-down list. Dynamic Viscosity Program. 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. Find your local dealer List of dealers Principles of cooperation Become our dealer Price lists. Breathing Air. 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. To express this concentration with metric units the density of water is needed.
