Easily calculate your water hardness level (soft, hard, very hard) to understand mineral content. Prevent limescale, protect appliances, and optimize water treatment with our free online tool. Just input calcium and magnesium concentrations for instant results!
Formula:
Total Water Hardness is typically measured in parts per million (ppm) as Calcium Carbonate (CaCO₃) equivalent. It's calculated based on the concentration of calcium (Ca²⁺) and magnesium (Mg²⁺) ions present in the water.
Formula:
Total Hardness (ppm CaCO₃) = (Calcium (mg/L) × 2.5) + (Magnesium (mg/L) × 4.1)
Where:
- Calcium (mg/L): Concentration of calcium ions (Ca²⁺) in milligrams per liter.
- Magnesium (mg/L): Concentration of magnesium ions (Mg²⁺) in milligrams per liter.
- 2.5: Conversion factor for Calcium to CaCO₃ equivalent.
- 4.1: Conversion factor for Magnesium to CaCO₃ equivalent.
This calculator provides an estimation of total hardness. For precise measurements, professional lab analysis is recommended.
