You can perform a PPM conversion easily provided you have two quantities in the same unit (or that you can convert into the same unit) or a percentage value. PPM means "parts per million," so to calculate it you divide the amount of the solute by the total amount of solution, them multiply by 10^6.

Parts Per Million (PPM) is a method of stating a component's tolerance value by specifying how many parts per million units a component may vary from its nominal value. This will all be explained below. Ways of Specifying Electronic Component Tolerance The tolerance of electronic components can be stated in one of 2 ways.
