Hello,
What it outputs depends on what you've entered. Have you got you latitude and longitude the right way round?
Rather frustratingly, GE decides to change the order it which it wants latitude and longitude depending on what you're trying to do.
The other possibility is that it's getting confused by what's entered and defaulting to co-ordinates of '0,0', which is in the ocean just off the coast of Africa.
Also, the position that GE moves to is not necessarily anything to do with the co-ordinates of placemarks themselves. If you're using <LookAt> tags in your KML (the converter doesn't put these in by the way), it will fly to whatever these tell it to.
If you're still having problems, post the latitudes and longitudes and I'll have a look...

Cheers,
Simon.
