App description

Water hardness online calculator

Usually the hardness of water is as follows:

mg/L Hardness
0 - 75 Soft
75 - 150 Moderately hard
150 - 300 Hard
300 and up Very hard

The hardness calculation caused by each ion is calculated by the following formula

Hardness (in mg/L) as CaCO3 = M2+ (mg/L) x (100 g/mol CaCO3 / atomic weight M2+)

The following calculator determines the hardness of the water to the concentration of divalent cation calcium, magnesium, manganese, iron, strontium.

Usage example

Ca2+ :2 mg/l

Mg2+ :4 mg/l

Fe2+ :2 mg/l

Sr2+ :0 mg/l

Mn2+ :20 mg/l

Click "Calculate" and output the result.

61.43367532152048 as mg/L calcium carbonate.

Note

The input value must be added to each box (i.e. if not, enter 0).
