App description

A compound is a pure substance composed of two or more different elements. The different atoms of the compound must exist in a certain proportion. In other words, the compound has a certain composition regardless of its source. In daily life, sodium chloride, and distilled water (water), are common compounds.

The conversion formula is based on 25 ℃ and 1 atmospheric pressure:

X ppm = (y mg/m3) (24.45)/(molecular weight) or Y mg/m3 = (x ppm) (molecular weight)/24.45.

Usage example

Fill in the "ppm" value (x) or "mg/m3" value (y) and the molecular weight of the compound. Then press the calculate button.

ppm: 5

mg/m3:

molecular weight: 2

Click "Calculate" to output the result.

ppm Value: 5

ppm Value: 0.41

According to molecular weight: 2
