For converting ppm by mole, the same equation can be used. This can be made clear by the following notation: 1ppm = 1µmole gas / 1 mole air = Vm/M * 1 1µg gas /1L air

PPM to Percent Conversion Calculator . PPM refers to parts per million. It represents the part of the whole number in units of 1/1000000. It is a dimensionless quality and is equal to 1×10-6. One parts per million(PPM) is exactly equal to 0.0001%. It is a unit used to express the dilute concentrations of substances in water or soil.

CO emissioner var i samtliga experiment lägre än 100 ppm. på syre- och kolfri basis (mol-%) vid förbränning av rörflen med hög askhalt och rörflen.

This is also known as molecular weight. The molar mass of an atom is its average atomic mass expressed in grams.

In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g.
