To use the same hardness scale above, you can simply convert your ppm or mg/L by dividing that number by 17.1 to find the gpg equivalent. So, for example, 130 mg/L or ppm would be 7.6 gpg, which is considered hard water.
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). Any water source that has more than 60 ppm is considered a hard water source.
The majority of findings are delivered as a number that reports the concentration of calcium carbonate or other equivalents for a given unit of water. The water hardness scale result may be expressed in parts per million (ppm), grains per gallon (gpg), or milligrams per liter (mg/L).
31 Μαΐ 2022 · To use the calculator simply put in your water hardness level either in gpg or ppm (same as mg/L) as well as your iron levels in ppm, the optimal water softener hardness setting will automatically be displayed below.
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.
30 Ιουν 2021 · 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.
One grain per gallon (gpg) is equivalent to 17.14 parts per million (ppm). Water hardness can be measured in gpg or ppm, but gpg is the most commonly used measurement. 20,000–80,000: This range signifies the grain capacity of most water softeners available on the market.
