Grain/Gallon Conversion Calculator
Use this calculator to convert parts per million (ppm) calcium carbonate (CaCO₃) to grains per gallon immediately for water treatment purposes.
When water falls into an alkaline range on the pH scale, calcium carbonate (CaCO₃) becomes an effective mode of treatment. Knowing what type of CaCO3 filter to use and the correct grains per gallon ratio is essential for effective water treatment. Use this calculator to convert parts per million (ppm) calcium carbonate to grains per gallon immediately, to ensure an effective level of treatment. In an instant, you’ll know the exact conversion rate, expediting time-to-treatment without any question of proper levels.
This is a plug-and-play calculator that’s free to use. Just input your variables, choose your desired method of measurement and the calculator will do the rest!
