This calculator determines how much of an additive you would need to add to a solution in order to achieve a specific ppm (parts per million). You have the option of using either ounces/gallons or grams/liters.
How Do You Find The Amount Needed To Get A Specific PPM
You would first take the amount of solution (either in liters or gallons) and convert it to either grams or ounces.
You would then multiply your solution times PPM, then divide by one million to find out how much you will need to add to your solution to achieve a specific PPM.
If you’re still confused, the calculator will provide an overview of the calculations it used to arrived at the answer.
