# Units of Conductance

I'm trying to understand how conductance that is measured in Siemens is equal to Amperes/Volt.

The SI units of Siemens is given to be in $$kg^{-1}m^{-2}s^3A^2$$ (link). I am not sure how this is related to A/V.

Could someone explain?

1 J is $$\1\ \rm kg\ m^2\ s^{-2}\$$.
1 C is $$\1\ \rm A\cdot s\$$.
So 1 V is $$\ 1\rm\ kg\ m^2\ s^{-3}\ A^{-1}\$$
