FAQ

What is the Total Hardness of Water?
The Total Hardness of Water formula is defined as the sum of the calcium and magnesium concentrations, both expressed as calcium carbonate. Total Hardness of Water is usually measured using the Milliequivalents per Liter for Molar Concentration. Note that the value of Total Hardness of Water is always negative.
Can the Total Hardness of Water be negative?
Yes, the Total Hardness of Water, measured in Molar Concentration can be negative.
What unit is used to measure Total Hardness of Water?
Total Hardness of Water is usually measured using the Milliequivalents per Liter[mEq/L] for Molar Concentration. Mole per Cubic Meter[mEq/L], Mole per Liter[mEq/L], Mole per Cubic Millimeter[mEq/L] are the few other units in which Total Hardness of Water can be measured.
