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.

The density of gas can be calculated by the Law of Avogadro's, which conversion ppm mg/m3 equal volumes of gases, at the same temperature and pressure, contain the same number of molecules. 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. Cleanroom solutions.

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.

Conversion ppm mg/m3

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. The conversion from PPM to percentage and back again is slightly simpler, we may need to use these calculations when deciding what calibration gas to use, say we have a 1. Our White Paper Article is available to download below, the information provides you with key information regarding how different regulation bodies use different types of units for different types of Workplace Exposure Limits WELs.
