The water hardness scale result may be expressed in parts per million (ppm), grains per gallon (gpg), or milligrams per liter (mg/L). Utilizing the Water Hardness Scale for Water Softener Selection.
Measuring water hardness can help you determine what kind of water softener will best meet your needs. To prepare for the next steps to soft water, learn how to assess your water hardness, understand the results and apply your findings.
For total water hardness calculation, we only use 2 cations: calcium ions (Ca2+) and magnesium ions (Mg2+). The total water hardness calculator takes into account both and expresses water hardness in terms of parts per million of CaCO3 (ppm) and GPG (grains per gallon).

To find out what size water softener you need, you must identify factors such as water hardness levels and daily water consumption habits, then use this information to choose the proper softener capacity.
The level of hardness is measured in grains per gallon (gpg) or milligrams per liter (mg/L). Water that registers between 0-1 gpg is considered soft; moderately hard water reads at 3.5-7 gpg; and any water with gpg over 7 is classified hard to very hard.
