si unit is-------------> siemens,denoted by 's'
The SI unit of conductance is the siemens (S), named after the German inventor and scientist Werner von Siemens. Conductance is the reciprocal of resistance and is a measure of how easily an electrical current can flow through a material.
The SI unit for conductivity is the siemens per metre. Conductivity is the reciprocal of resistivity, whose SI unit is the ohm metre.

Siemens
The mho is an obsolete unit of measurement for conductance, which has been replaced by the siemens(symbol: S), in SI. Conductance is the reciprocal of resistance, so 300 S, is exactly the same as 1/300, or 3.33 milliohms.
First of all, the correct spelling is 'siemens' (symbol: S), which is the SI unit of measurement for conductance -the reciprocal of resistance. The mho is simply an obsolete unit for conductance, and is exactly equivalent to the siemens.
Specific conductance is the conductance of a specified length of a substance, typically 1 cm, while equivalence conductance is the conductance of all ions produced by one mole of an electrolyte in solution. Specific conductance is a property of the substance itself, whereas equivalence conductance is a property of the electrolyte in solution.
Old units for electrical conductivity (EC)SI units of electric resistance and electric conductance are ohm (Ω) and siemens (Si). The unit mho ("ohm" in reverse order) for conductance should no longer be used (1 mho = 1 Si). abohm and abmho are older units from the centimetre-gram-second electromagnetic system. statohm and statmho are from the centimetre-gram-second electrostatic system.see also this forum http://landviser.us/phpBB3/viewtopic.php?f=4&t=3&p=19#p19The question is about conductivity, not, as the above answer, conductance. The siemens in the unit of measurement for conductance, whereas the siemens per metre is the unit for conductivity.
Specific conductance is directly proportional to the concentration of electrolyte, while equivalent conductance is inversely proportional to the concentration of electrolyte. This is because specific conductance is the conductivity of a solution normalized to a unit concentration, while equivalent conductance is the conductivity of a solution containing one equivalent of the electrolyte.
The correct spelling is siemens, and it is the SI unit for conductance -the reciprocal of resistance. The mho is simply an obsolete unit for the same thing, and is numerically equal to the siemens.
If conductance decreases, the current flowing through the circuit will also decrease. Conductance is the inverse of resistance, so decreasing conductance means increasing resistance, which impedes the flow of current.
