We went through Facebook Pages, Groups and Profile and Their Differences earlier. This blog post is to know more about the Facebook Conversions and merging of these popular facebook features
At different points in time, we might have been looking to convert the features of Facebook from one form to another. Facebook profile to a page, a group to a page, or a page to a group, etc. There are multiple reasons to do that.
One such example is being unaware of the difference between the features, Starting a page for a community/group and later realise that a Facebook group should have been started rather than a page.
Converting Facebook profile/account into a Page
Yes, check this Facebook Help link to know "How to convert personal account to a Facebook Page."

Converting Facebook Fan page into a Group

It is not possible.
Converting Facebook Group into a Page
It is currently not possible to convert Facebook groups into Pages. We recommend that you create a Page and notify your group members about it.
Even though there is no limit to the number of people your group can have, you will not be able to send your group a message if it has more than 250 members. If your group has more than 250 members, notify them by posting in the group.
Instead, create a new Page and notify your group members that you'll be using the Page instead of the group going forward.
