On-line calculation of compounds: conversion between ppm and mg/m^3

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
