Elevation Seems to Switch Between Feet and Meters

[Finbar MacAlion]

Hello All,

Please Help!

1. I create a "Google Earth Ready" 3d Model in Sketchup.
2. Uploaded and accepted to Google Earth.
3. I then want to get HTML code for embedding into website so i go to
the customise google earth view page

http://maps.google.com/maps/empw?url=http:%2F%2Fmaps.google.com%2F%3Fie%3DUTF8%26ll%3D55.219034,-7.366518%26spn%3D12.57866,43.286133%26t%3Df%26z%3D5%26vpsrc%3D6%26ecpose%3D55.21930576,-7.36651719,2057514.86,0.001,0,0%26output%3Dembed&hl=en

4, I navigate and set the view position that want to view my model
which produces this code

<iframe width="640" height="480" frameborder="0" scrolling="no"
marginheight="0" marginwidth="0" src="http://maps.google.com/?
ie=UTF8&amp;t=f&amp;ecpose=55.31626671,-7.37291243,18.97,66.041,90,0&amp;ll=55.32578,-7.335257&amp;spn=0.023438,0.054932&amp;z=14&amp;output=embed"></
iframe><br /><small><a href="http://maps.google.com/?
ie=UTF8&amp;t=f&amp;ecpose=55.31626671,-7.37291243,18.97,66.041,90,0&amp;ll=55.32578,-7.335257&amp;spn=0.023438,0.054932&amp;z=14&amp;source=embed"
style="color:#0000FF;text-align:left">View Larger Map</a></small>

5. However when I paste this to my site or online HTML editor, then
view the results, the elevation changes to a higher position and thus
renders the Model out of sight.

WHY???

This does not happen every time and I think it may have something to
do with Units of feet or meters

WHAT CAN I ADD, (and where), OR DELETE TO THE CODE TO STOP THIS
HAPPENING ?

Please help

Thank You
