Water Hardness PPM to GPG Calculator & Chart [2023]

Last updated on August 28th, 2023

PPM to GPG Calculator: In the United States, water hardness is commonly express using two units of measurement ppm to gpg.

 ppm (parts per million) 

gpg (grains per gallon)

Parts per million, often referred to as American degrees, represents the concentration of a specific substance in water. For water hardness, it signifies the presence of 1 milligram of calcium carbonate (CaCO3) dissolved in one liter of water.

On the other hand, grains per gallon is another unit used to quantify water hardness. It is defined as the amount of calcium carbonate (CaCO3) equivalent to 1 grain, dissolved in one gallon of water.

Useful Resources for PPM to GPG Conversion

• PPM to GPG Water Hardness Calculator: This calculator simplifies the process of converting water hardness from (PPM) to (GPG). By inputting the PPM value, users can quickly determine the equivalent GPG measurement. The calculator ensures accurate results, making it a valuable tool for water quality assessments and treatment.
• PPM to GPG Water Hardness Chart: Covering a range from 1 to 1000 PPM, the chart categorizes water hardness levels.
• soft (0-60 PPM), moderately hard (61-120 PPM), hard (121-180 PPM) and very hard (181+ PPM) . This chart facilitates easy identification of water hardness levels for different applications.
