Converting from Degree hardness (°dH) to Milligram per liter (mg/L) | Mineralization

What is Degree hardness (°dH)

Degree hardness (°dH) is a unit used to measure the concentration of minerals in water, specifically the concentration of calcium and magnesium ions. Water with a higher degree hardness value contains more minerals and is considered "hard" water.

What is Milligram per liter (mg/L)

Milligram per liter (mg/L) is a unit of measurement used to represent the concentration of a substance in water. In the context of mineralization, mg/L is commonly used to measure the concentration of minerals such as calcium and magnesium in water.

Conversion Formulas

The default conversion between °dH and mg/L is as follows:

• 1 (°dH) = 17.85 (mg/L)
• 1 (mg/L) = 0.05602241 (°dH)

Other conversions include:

• 2 (°dH) = 35.7 (mg/L) or 2 (mg/L) = 0.1120448 (°dH)
• 4 (°dH) = 71.4 (mg/L) or 4 (mg/L) = 0.2240896 (°dH)
• 5 (°dH) = 89.25 (mg/L) or 5 (mg/L) = 0.280112 (°dH)

Examples

1. Convert 3 °dH to mg/L:

3×17.85=53.55 mg/L

2. Convert 50 mg/L to °dH:

50×0.05602241=2.80112 °dH

3. Convert 6 °dH to mg/L:

6×17.85=107.1 mg/L

Performing these conversions allows you to accurately measure and understand the mineral content of water, which is crucial for various applications such as water treatment, brewing, and agriculture.
