Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent. What is Soft Water? Soft water is defined by American National Standards NSF/ANSI 44 and NSF/ANSI 330 as water containing <1 grain of hardness per gallon (or <17.1 mg/L hardness). 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.

Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm. Work out A water supply with a hardness of 100 ppm contains the equivalent of 100 g of CaCO3 in 1 million g of water or 0.1 g in 1 L of water (or 1000 g of water since the density of water is about 1 g/mL). Regarding this, how do you calculate the hardness of water in ppm CaCO3? Milligrams per litre (mg/l): The number of milligrams of calcium carbonate 2021-04-22 · Degrees of Hardness in the PPM of Hard Water Soft Water. Soft water has fewer than 75 ppm (parts per million) of minerals dissolved in it.

Jumping mg/L by 17.1 will change it to GPG. A “grain” of water hardness is comparable to 1/7000th of a pound.
