First off, centrifugal force isn't necessarily real.  But anyway centripetal force pulls towards the center of a rotating object while centrifugal is supposed to do the opposite and pull outwards from the center of a rotating object.

The centrifugal force is "fictitious" but still does in a sense exist. It appears in rotating frames only, whereas centripetal force has no such requirement.

Edited the blatant typos 19/4.

I just looked at a map 14 years ago!

Last I checked, it was about three inches, but it depends on how zoomed in you are.

Lucky, three60 meant that centrifugal forces only appear in a rotating frame, whereas centripetal forces have no such requirement. It's an extra term that comes up when you consider the reference frame of the person being spun around.
