A metaphor means that two things are the same in all ways. For example, He is a pig means that he is like a pig in many ways: size, appetite, manners, etc.
A simile, however, means that the two things are the same in 1 way. For example, He is fat like a pig or He is as fat as a pig means that he is very fat.
