I used to use 2rss' ATOM to RSS converter like this - http://www.2rss.com/atom2rss.php?atom=http://sudhir-lp.blogspot.com/atom.xml. However, quite often, I used to get advertisements.
If you do want to stick to RSS feed only, you could try the steps given in http://www.wcc.vccs.edu/services/rssify/rssify.php. They don't put any ads in the converted feed. They render RSS 0.92.
At the moment, I'm using FeedBurner's service and my feed is available from http://feeds.feedburner.com/sudhir_lp. More on that later.
