Keep in mind that because Mercator is a variable scale projection there 
is no direct relationship between zoom level and scale.  At a typical 
resolution computer screen z13 for example can be somewhere between 
about 1:70000 (Equator) and 1:8000 (northern Greenland).

Something in that direction has already been discussed:
