convert pages to posts

I’m cleaning up my newbie-blog and I know this is obvious to some and I have done a fair amount of searching, but still: is there a way to convert pages to posts?

I have made some errors in my initial posting [paging?] and need to clean things up as I climb the learning curve, but I have dozens of pages that should be posts. Is there a way to convert them?
