Ppm calculation formula pdf

In general, though, you can always calculate PPM using one approach and a simple formula. The first thing you need to do is get a measurement of the amount of solute or substance you're interested in, then get the same type of measurement for the whole solution, e.g.

you want a volume of your solute and a volume of your solution, or a mass of both. Then you can use the following formula to find the concentration:

\(\text{Concentration in PPM} = \frac{\text{Amount of solute}}{\text{Amount of whole solution}} × 10^6\)

You can break it down into a two-step process if that helps: First, divide the amount of the solute by the amount of the whole solution to get a "parts per 1" measurement for the concentration.

From this point, you're simply multiplying by 1,000,000 to change it into a PPM measurement, or alternatively (if it's better suited to the concentration you're working with) you could multiply by 100 to turn it into a percentage, or 1,000,000,000 to turn it into a parts per billion (PPB) value.

Just remember that you need to keep
