Correct for the ratio of Vin/Vout and Iin/Iout.
For powers it becomes 20lgPin/Pout.

The latin for Mercury is "Hydrargirum". Incidently, in Europe the periodic chart 
is known by the name of its discoverer, the great Russian chemist D.I. Mendeleev,
hence - "the Mendeleev chart", and because of multylingual nature of european 
comunity the tradition calls for using the latin names for the elements.
