So turns out google found it for me after a while ..
Converted into c# it looks like this
public LatLng displayToCoordinate(Point point, int zoom)
{
// longitude
double longitude = (point.X * (360 / (Math.Pow(2, zoom) *
256))) - 180;
// latitude
double latitude = point.Y * (2 / (Math.Pow(2, zoom) *
256));
latitude = 1 - latitude;
latitude = latitude * Math.PI;
//latitude = rad_deg(Math.Atan(Math.Sinh(latitude)));
latitude = rad_deg(Math.Atan(Math.Sinh(latitude)));
LatLng coord = new LatLng(latitude, longitude);
return coord;
}
private double rad_deg(double p)
{
return p * (180 / Math.PI);
}
