Parts per million works like percent by mass, but is more convenient when there is only a small amount of solute present. PPM is defined as the mass of the component in solution divided by the total mass of the solution multiplied by 10 6 (one million): A solution with a concentration of 1 ppm has 1 gram of substance for every million grams of solution. ...
