Hardness - an overview | ScienceDirect Topics

The convention has been to define hardness as milligrams per liter of calcium carbonate: (6.13) Hd = 100.09 ( Ca ( mg / L ) 40.08 + Mg ( mg / L ) 24.305 ) Hardness is of limited scientific value because of treating all dissolved alkaline earth ions as if they were calcium, but it does give a good sense of the quantity of dissolved carbonate and, as such, is a useful water quality parameter.
