You cannot convert ohms to uS/cm because they are completely different kinds of quantities.
Ohms are the SI unit of resistance (R). Siemens (S) are the units of conductance (G - defined as 1/R). So you can convert ohms to S by taking the reciprocal - for example 5 ohms = 0.2S.
S/m are the units of conductivity. This is a property of an electrically conducting material, and is distinct from conductance, which is a characteristic of an electric circuit (equal to I/V).
The reciprocal of conductivity is resistivity measured in Ohms-metres - just another way of characterising a material. So conductivity can be converted to resistivity by taking the reciprocal.
You can find the conductance of a particular piece of conductor by multiplying together conductivity (s) and cross sectional area (A), and dividing by length (L). This will give conductance in S. Resistance R is then the reciprocal of this.
Briefly, R = L/(A*s)
or s = L/(A*R)
All units in these calculations should be the SI base units. s should be expressed in S/m with SI multipliers where appropriate. µs/cm looks like a cgs expression. cgs has not been used by the scientific community for several decades (I can remember last using that system when at school in the 1960s - nearly half a century ago !)
