Grain of hardness
WebJan 15, 2024 · 👨🔬 Water hardness is measured in GPG (grains per gallon). You can convert GPG to mg/L (milligrams per liter) or parts per million (PPM) easily. For example, 7 GPG of hardness is equal to 120 PPM. Parts per million and milligrams per liter are interchangeable, so 120 PPM = 120 mg/L.
