EMs are relative units. They are relative to a users preference setting, typically in px, but they scale based on what size the user has set. Some one with poor eye sight might set their browser default at 30px. By using ems your site will automatically honor the users wish to have a large font size so they can read it. (Hopefully you build your site in such a way that this didn't break it).
Also, in the past, some browsers would not scale font set in px when a user used the zoom feature in the browser. Ems scaled.
