The chemical formula calculator is particularly helpful for establishing the percentage of each element that exists in a fertilizer or other chemical product. It is also helpful when working with formulas expressed in mole (e.g. pH and EC Standards).
Simply enter the chemical formula and its purity and the calculator does the rest.

Usage: Enter your chemical formula into the given box, making sure to capitalise the correct elements, using subscript and the correct brackets where applicable () and [] E.g.
