1 GPG = 17.1 PPM
1 percent is 10,000 ppm .06 percent = (.06 x 10,000) = 600 ppm 90 ppm = (90 / 10,000) = 0.009 percent 0.06 percent is not the same thing as 90 ppm. This is not a math problem. You have to change the material. That's a chemistry problem.
The hardness limit of water is typically referred to as the maximum amount of dissolved minerals, such as calcium and magnesium, that can be present in water before it is considered hard. This limit is often expressed in terms of grains per gallon (gpg) or parts per million (ppm), with water classified as hard if it exceeds around 7 gpg or 120 ppm of hardness minerals.
To convert 0.5 percent to parts per million (ppm), you multiply by 10,000. So, 0.5 percent is equal to 5,000 ppm.
To convert parts per billion (ppb) to parts per million (ppm), you divide by 1000. So, 28 ppb is equal to 0.028 ppm.
In order to convert ppm to pH, one must first understand that 1 ppm is equivalent to 1mg/L. For example, if one wanted to convert 20mg/L into a pH one would use the equation 0.02g/36.45g/mole which is equal to a pH of 3.2.
0.5Mm = 50 PPM
Multiply ppm by 10000.
322 ppm = 0.0322%
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
*1000
Divide ppm by 10,000:50,000 / 10,000 = 5 %
1 percent is 10,000 ppm .06 percent = (.06 x 10,000) = 600 ppm 90 ppm = (90 / 10,000) = 0.009 percent 0.06 percent is not the same thing as 90 ppm. This is not a math problem. You have to change the material. That's a chemistry problem.
Divide by 1000.
Multiply by 10,000: 0.0025 x 10,000 = 25 ppm
