You cannot since there is no equivalence.
MicroSiemens is a unit of measurement of electrical conductance while PPM refers to parts per million and is a pure number (ratio). The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
1 GPG = 17.1 PPM
ppm x 3to the power of 6= kg
mho/cm = S/cm = 10^3 mS/cm
Multiply by 10,000: 0.5 x 10,000 = 5,000 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.
To convert from picosiemes to microsiemens, you have to divide by a million. To convert from "per meter" to "per centimeter", you would multiply by a million. The end result is that you divide by 10,000.
Siemens is the reciprocal of ohm. You can convert from milliohms to ohms, then take the reciprocal. The answer will be in Siemens.
0.5Mm = 50 PPM
Multiply ppm by 10000.
322 ppm = 0.0322%
1 GPG = 17.1 PPM
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
ppm x 3to the power of 6= kg
Divide ppm by 10,000:50,000 / 10,000 = 5 %
Divide by 1000.
Multiply by 10,000: 0.0025 x 10,000 = 25 ppm
