Here is a quick hard water ppm chart that gives you a spectrum of water hardness in parts per million (ppm): Scale Of Water Hardness (From Soft To Very Hard Water) The internationally recognized water hardness scale recognizes 4 water hardness classes; from soft, moderately hard, hard, to very hard.
- PPM to GPG
Water hardness in the US is measured either in ppm (parts...
- PPM to GPG
GPG = Grains Per Gallon ppb = Parts Per Billion ppm = Parts Per Million Ohms – µmhos – ppm – ppb - GPG Water Quality Conversion Chart (as CaCO 3) Dissolved Solids 400 2500 1250 73 12.6 1.4 500 2000 1000 58 12.5 1.5 667 1500 750 44 12.4 1.7 1,000 1000 500 29 12.2 1.9 1,429 700 350 20 12.1 2.0 2,000 500 250 15 11.9 2.2 4,000 250 125 7 11.6 2.5
4 Ιουν 2022 · The calculator below can be used to convert between grains per gallon (gpg), parts per million (ppm), and milligrams per liter (mg/L). Simply input the value of your starting unit in the corresponding box, it will automatically convert to the other units.
Water hardness can be expressed in many different units, including French degrees, German degrees, Clark degrees, grains per gallon, mg/L CaCO3 (calcium carbonate), and ppm (parts per million). General conversions are below:
4 Μαρ 2024 · The Water Hardness Conversion Calculator facilitates conversions between different units of water hardness, including parts per million (ppm), grains per gallon (gpg), French degrees (°f), and German degrees (°dH).
Another unit often used to measure water hardness is parts per million (ppm). The relationship between GPG and ppm is quite direct. For our water hardness test results specifically, 1 grain per gallon roughly translates to 17.1 ppm. So, if you have a reading in ppm, you can easily convert it to GPG using this ratio.
29 Ιουν 2023 · Understanding the conversion between ppm and gpg is essential for assessing water hardness levels and choosing the appropriate water treatment solutions. Whether you need to convert ppm to gpg or vice versa, the conversion formula of dividing by 17.118 provides a straightforward method.
