Ronjomp,
To use them in a kml all you need to do is
to use them in reverve order that is long first
as 111.0916667 33.67
For example outputting the following
is sufficient to create a placemark at your point:
<Placemark>
<name>YourPoint</name>
<Point>
<coordinates>111.01966667,33.67,0</coordinates>
</Point>
</Placemark>
note: no space after the comma.
