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.
To convert from mhos per centimeter to microsiemens per centimeter, you can use the conversion factor 1 mho/cm = 1000 µS/cm. Multiply the value in mhos/cm by 1000 to get the equivalent value in microsiemens/cm.
To convert 0.06% selenium to ppm, you need to multiply by 10,000. Therefore, 0.06% selenium is equivalent to 600 ppm. To convert 600 ppm to 90 ppm, you would need to dilute the solution by a factor of 6.67 (600 ppm / 90 ppm).
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.
To convert parts per million (ppm) of a substance to grains per gallon (gpg), you need to know the atomic or molecular weight of the substance. Once you have this information, you can use the formula: gpg = ppm x (atomic/molecular weight/7000).
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.
To convert from mhos per centimeter to microsiemens per centimeter, you can use the conversion factor 1 mho/cm = 1000 µS/cm. Multiply the value in mhos/cm by 1000 to get the equivalent value in microsiemens/cm.
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 %
To convert 0.06% selenium to ppm, you need to multiply by 10,000. Therefore, 0.06% selenium is equivalent to 600 ppm. To convert 600 ppm to 90 ppm, you would need to dilute the solution by a factor of 6.67 (600 ppm / 90 ppm).
Divide by 1000.
Multiply by 10,000: 0.0025 x 10,000 = 25 ppm
