Water hardness Conversion Calculator

The water hardness is using American degree equivalent to mg/L. Water hardness(mg/L)=Ca(mg/L)×2.497 + Mg(mg/L)×4.118 Classification of hard water and soft water is based on WQA (Water Quality Asociation). ※This site shall not be liable for any damages arising out of the use this library The water hardness indicates how much calcium and magnesium are in the water. Further information on water hardness can be found on our information pages. To express the amount of calcium and magnesium, ie the water hardness in numbers, there are different units. The hardness is an arbitrary division into three hardness ranges from soft to hard The calculation of the hardness caused by each ion is performed by the following equation:. Hardness (in mg/L) as CaCO 3 = M 2+ (mg/L) x (100 g/mol CaCO 3 / atomic weight of M 2+) .

For the calculation of the magnesium type 30 into the field in front of mg Mg 2+ /l. After another click you see the result for magnesium (e.g. English degree of hardness: 8.7 °e or 1.23 mmol/l). You have to add both results to receive the total hardness, e.g. English degree of hardness: 33.2 °e or 4.72 mmol/l. Remarks With a hard water calculator, you can find overall permanent hardness. The calculator uses the formula below: TOTAL PERMANENT HARDNESS = MAGNESIUM HARDNESS + CALCIUM HARDNESS Water Hardness. GH is the unit used to tell us the General hardness of the water. Or how much Calcium and/or Magnesium are dissolved in the water. Only Calcium and Magnesium are measured and not the overall amount of dissolved solids. The GH level isn't really of importance unless you want to breed your fish or unless it is extremely high

The effects of hard water on your home, hair and skin can be detrimental. Use our water hardness calculator to find out if you're living in a hard water area Grains per gallon is the business standard approach for talking about water hardness. Jumping mg/L by 17.1 will change it to GPG. A grain of water hardness is comparable to 1/7000th of a pound. Formula to measure no of grains to be removed: If hardness is in MG/L or PPM , convert it into GPG by dividing it with 17.1

Home » Water Softener Sizing Calculators » Total Hardness Calculator. Total Hardness Calculator . How do you determine the total hardness of your water? Enter the hardness (ppm) of each applicable substance in the form below. Hardness will be shown as equivalents in Calcium Carbonate (CaCO3). The most common substances are listed at the top. Pseudo Hardness PsH. The three quantities, TH, CH and NCH form the standard terminology of water hardness in almost all textbooks. However, a problem appears if the measured alkalinity (i.e. CH) exceeds the total hardness: CH > TH. In this special case 4 becomes senseless Steel Hardness Conversion Table. This table shows approximate hardness of steel using Brinell, Rockwell B and C and Vickers scales. These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness. The right hand column show an approximate equivalent tensile strength Scientists measure water hardness in parts per million (ppm) or grains per gallon (gpg).

Another convenient conversion is that of Brinell hardness to ultimate tensile strength. For quenched and tempered steel, the tensile strength (psi) is about 500 times the Brinell hardness number (provided the strength is not over 200,000 psi).

This page is designed to explain to the customer what is considered to be hard water. It is very important that you determine your hardness before buying your water treatment equipment. Water softeners are much more efficient when you get the correct size Water hardness can be expressed in many different units including French degrees, German degrees, Clark degree, grains per gallon, mg/L CaCO3 (calcium carbonate), and ppm (parts per million). General conversions are below: 1 ppm = 1 mg/L CaCO3 1 ppm = 0.058 grains/US gallon 1 ppm = 0.07 Clark degrees 1 ppm = 0.10 French degrees 1 ppm = 0.056. Hardness conversion calculator for Rockwell, Brinell, Vickers, Shore Scleroscope, and Tensile Strength The Hardness Conversion Calculator is particularly handy. Enter a from value, select the from units, enter the to units, and G-Wizard will give you a value (if there is one) in the new hardness units

This can be done using the calculator above, or it can be done using a standard calculator or hand calculation. Finally, you need to analyze the results. PPM is used to bring a really small number into a more realistic number that you can visualize and analyze In most natural waters, water hardness will tend to precipitate in case of increasing water temperature or ↑pH, for example as limescale (CaCO 3). For many technical applications, it is thus neccessary to reduce the water hardness of process water by appropriate measures, for example by → ion exchange softening Convert hardness to equivalent hardness from different scales. Black and white version of conversion table for determining equivalent hardness for Rockwell, Rockwell Superficial, Vickers, Brinell, Scleroscope and ultimate tensile strengt Water hardness The hardness of water is due to the presence of calcium and magnesium minerals that are naturally present in the water. The usual signs of a hard water supply are scaling inside kettles, poor lathering of soaps and scum. What is water hardness?

Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types A water softener is an ion-exchange device - it grabs on to calcium and magnesium ions (aka hardness) and exchanges them for sodium. Well, the sodium carries the same electrical charge as the hardness. So the TDS reading of hard water and soft water is pretty much identical even if the water has been softened perfectly

67 Water Hardness and pH Water is classified as either soft or hard: Soft water contains relatively few minerals and lathers easily. Hard water is rich in minerals such as calcium and magnesium, which is the cause of scale in kettles. Water hardness is usually expressed as the number of parts per million (ppm) of calcium carbonate present. R.O. Ansell, in Encyclopedia of Analytical Science (Second Edition), 2005. Water Hardness Measurement. Water hardness is the total calcium and magnesium ion concentration in a water sample and is expressed as the concentration of calcium carbonate.
