Converting from Parts per million (ppm) to Degree hardness (°dH)

What is Parts per million (ppm)

Parts per million (ppm) is a unit of measurement used to represent the concentration of one substance in a million parts of another. It is commonly used in various fields such as environmental science, chemistry, and water quality testing to quantify the amount of a particular substance present in a solution.

What is Degree hardness (°dH)

Degree hardness (°dH) is a unit of measurement used to quantify the mineral content, specifically calcium and magnesium ions, in water. It indicates the water's ability to form scale and soap scum. The higher the degree hardness value, the "harder" the water is considered to be.

Conversion Formulas

The default conversion formulas between parts per million (ppm) and degree hardness (°dH) are as follows:

1 (ppm) = 0.05602241 (°dH)

1 (°dH) = 17.85 (ppm)

Examples

1. Convert 3 ppm to °dH:

3 ppm×0.05602241=0.1680672 °dH

2. Convert 6 °dH to ppm:

6 °dH×17.85=107.1 ppm

3. Convert 9 ppm to °dH:

9 ppm×0.05602241=0.5042017 °dH

4. Convert 3 °dH to ppm:

3 °dH×17.85=53.55 ppm

By using these conversion formulas, you can easily switch between parts per million and degree hardness to analyze the mineral content of water and other solutions.
