So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: 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). Symptoms of Hard Water include: Water hardness can be measured in gpg or ppm, but gpg is the most commonly used measurement. 20,000–80,000: This range signifies the grain capacity of most water softeners available on the market.

33,5 ppt. 7,3 – 7,7 / 2,6 – 2,7.

If the water is clear and there are no signs of scaling, there is no compelling reason to have to maintain a TA in the 80-120 PPM. Adjust the pH to optimum. If the TA is too high (as expected in this case) and the water is clear and there is no scaling present, all that the high TA will do is to help stabilize the pH even more than usual.

1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 .

Other human data: Exposures to 30 ppm have been reported to cause intense coughing fits and exposure to 40 to 60 ppm for 30 to 60 minutes or more may cause serious damage [ILO 1971]. A concentration of 34 to 51 ppm has been reported to be lethal in 1 to 1.5 hours [Freitag 1941] while 14 to 21 ppm has been suggested as being dangerous within 0.5 to 1 hour [NPIRI 1983].

Ppm testing is an effective way to measure substances like chlorine and salt. For reference, 1 ppm is the equivalent of 1 or 2 grains of sugar dissolved in a bathtub full of water. Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent. What is Soft Water?
