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. Conversion ppm mg/m3 can also be expressed as parts per million ppm or parts per billion ppb by using a conversion factor.

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. Converts gas concentration units to other units.

This unit expresses the concentration in one cubic metre of air equivalent to 1L or mL of a substance in terms of its mass measured in milligrams, 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, 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. What are the conversion factors for the common major air pollutants?
