      Hardness is usually reported in milligrams per liter (mg/L) or grains per gallon (gpg). One mg/L is equivalent to one part per million (ppm), or one part of hardness for every one million parts of water. Grains per gallon is a less accurate measurement defined as 1 grain (64.8 milligrams) of calcium carbonate dissolved in 1 U.S. gallon of water.
