The values in an NPK fertilizer label are related to the concentrations (by weight) of phosphorus and potassium elements as follows:
The N value in NPK labels represents actual percentage of nitrogen element by weight, so it does not need to be converted.
So, for example, an 18−51−20 fertilizer contains by weight
As another example, the fertilizer sylvite is a naturally occurring mineral consisting mostly of potassium chloride, KCl. Pure potassium chloride contains one potassium atom (whose atomic mass is 39.09 g/mol) for every chlorine atom (whose atomic mass is 35.45 g/mol). Therefore, pure KCl is 39.09/(39.09 + 35.45) = 52% potassium and 48% chlorine by weight. Its K value is therefore 52/0.83 = 63; that is, a fertilizer that gets all its potassium from K
2O and has the same potassium contents as pure KCl would have to be 63% K
2O. Pure KCl fertilizer would thus be labeled 0-0-63. Since sylvite contains other compounds that contribute no N, P, or K, it is usually labeled 0-0-60.
