Hi.

http://code.google.com/apis/maps/documentation/javascript/maptypes.html#WorldCoordinates

World Coordinates range from 0 to 256 for both x and y values.
At zoom level 0 those world coordinates are the same as the pixel
coordinets that you want.

At higher zoom levels simply take each x and y value and multiply by 2
to the power of the zoom level.
