It can pose critical problems in industrial settings, where water hardness is 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]. 1 cubic foot of water weighs 62.3832 lb 1 gallon of water weighs 8.34 lb (Length, 1 liter of water weighs 1,000 gm 1 mg/L = 1 part per million (ppm) 1% = 10,000 ppm ft 2 = square feet and ft 3 = cubic feet 1 mile = 5,280 feet (ft) 1 yd3= 27ft3 =and 1 yard = 3 feet 1 acre (a) = 43,560 square feet (ft2) 1 acre foot = 325,851 Cost, $ =gallons 2021-01-24 Find helpful customer reviews and review ratings for HM Digital TDS-EZ Water Quality TDS Tester, 0-9990 ppm Measurement Range, 1 ppm Resolution, 3% Readout Accuracy at Amazon.com.

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. Depending on your water hardness number, daily water use and the number of people in the home, you may need a smaller—or larger—grain capacity softener.

Death within 1-3 minutes. 35,000 ppm A method of reporting the concentration or "equivalent" weight of an ion or substance in a given volume of water as "ppm as calcium carbonate". Reporting the concentration of ions as "ppm as calcium carbonate" is popular by ion exchange chemists for the calculation of ionic loading of cation or anion resins. 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.
