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, conversion ppm mg/m3. Either directly enter the name of the gas, or select it from the pull-down list.

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 for every chemical. The temperature of the atmosphere also has an influence on the calculation.

Another way of expressing this value is ppmv.

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.

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? And how can one be converted to the others? Chemical concentrations in the air are typically measured in the mass units of the substance milligrams, micrograms, nanograms, picograms per volume of air cubic metre or cubic feet. However, these concentrations can also be expressed as parts per million ppm or parts per billion ppb by volume through a conversion factor. This is based on the molecular weight of the chemical, which is different between pollutants, and the atmospheric temperature and pressure. A temperature of 25 degrees Celsius and pressure of 1 atmosphere are what is normally assumed for the conversion factor. The number An exception to the conversion process is the air pollutant particulate matter PM 10 and PM 2.

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. Within the personal and portable Instrument sold by ION Science these calculations are done within the instrument software so no manual calculations are needed to convert the units.

With this equation it comes clear that the percentage notation by ppm is much more useful, because the independency of the temperature and pressure. Molecular weight.
