1ppm = 1/1000000. 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.
