Blogger does not currently support importing a wordpress blog, but you can still do it easly:
Login to your WordPress account and navigate to the Dashboard for the
blog that you'd like to transfer to Blogger. Click on the Tools tab > Export link, then download the WordPress WXR export file by clicking on Download Export File and save this file to your local machine.
2. Go to Wordpress2Blogger, browse to that saved document and click Convert
and save that file to your local machine. In this file will be the
contents of your posts/comments from WordPress in a Blogger export file.
3. Then from your dashboard: Settings > Basic tab and click "Import" to import the converted file.
