A siemens is a unit of conductance or admittance, expressed as the reciprocal of resistance or impedance. (Siemens = 1/ohms)
One microsiemens is 1 megohm.
150--600 microsiemens per meter
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.
Unit of dm water conductivity is microsiemens/cm
31200 microsiemens/cm
Siemens is the reciprocal of ohm. You can convert from milliohms to ohms, then take the reciprocal. The answer will be in Siemens.
Standard solutions are used to check instruments and methods of analysis.
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.
mho/cm = S/cm = 10^3 mS/cm
Multiply x .12 to get cm2 or by 1.2 to get the m2
Up until about the late 1970's the units of EC were micromhos per centimeter (µmhos/cm) after which they were changed to microSiemens/cm1 µS/cm = 1 µmho/cm.CorrectionThis is true, but the answer and the question illustrate why the "mho" was changed to the "siemens": it's too easy to confuse "mho" and "ohm" Incidentally, the mho was intended to be the ohm spelled backwards, to illustrate that the mho is the inverse of the ohm, but as we see, this turned out to be more confusing than helpful. The original question is how to convert µS cm to ohm cm. I assume that the original poster wanted to convert ohm cm to µS/cm (microSiemens divided by centimeters, not multiplied)In that case, the answer is that S/cm are the inverse of Ohm cm. So:1/ 1 megaohm cm = 1 microS/cm
A water distilled in a platinum installation - Kohlrausch water - with an electrical conductivity of less than 0,055 microSiemens/cm at 25 0C.
