Degree hardness (°dH) to Parts per million (ppm) converter

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

What is Degree hardness (°dH)

Degree hardness (°dH) is a unit of measurement used to quantify the concentration of mineral ions, such as calcium and magnesium, in water. It indicates the amount of dissolved minerals in water, which can impact its taste, texture, and suitability for various applications.

What is Parts per million (ppm)

Parts per million (ppm) is another unit of measurement that describes the concentration of a substance in water. It represents the ratio of the mass of the substance to the total mass of the water sample, expressed in millionths. In the context of mineralization, ppm is used to quantify the mineral content of water.

Conversion Formulas

To convert from °dH to ppm: ppm=°dH×17.85

To convert from ppm to °dH: °dH=17.85ppm​

Examples

  1. Converting 7 °dH to ppm:

ppm=7×17.85=124.95

  1. Converting 11 ppm to °dH:

°dH=17.8511​≈0.616

  1. Converting 4 °dH to ppm:

ppm=4×17.85=71.4

Conclusion

Use the provided conversion formulas to accurately convert between degree hardness (°dH) and parts per million (ppm) to better understand the mineralization levels in water sources.
