In water solution, the concentration C in parts-per million (ppm) is equal to 1000 times the concentration C in grams per kilogram (g/kg) and equal to 1000000 times the concentration C in grams per liter (g/L), divided by the water solution density at temperature of 20ºC 998.2071 in kilograms per cubic meter (kg/m 3) and approximately equal to Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm. The initial set of water tests can provide a good overview of your well water quality if you know how to interpret the results. The information below provides a starting point for evaluating your water quality.
