Key Differences

Michael is a traditional male name with Biblical origins, stemming from the Hebrew name Mikha'el, which means "Who is like God?". On the other hand, Mike is a diminutive form of Michael and serves as a more informal or affectionate version of the name.
While Michael carries with it a sense of formality and might be used in official documents or formal introductions, Mike offers a sense of familiarity, often used among friends, family, or peers. Both Michael and Mike, however, refer to the same individual, and it's up to personal preference as to which version is used and when.
For instance, a person named Michael might introduce himself as Mike in a casual setting but use Michael in a professional context. Though both Michael and Mike are intrinsically linked, their usage can convey different degrees of intimacy or formality, depending on the context.
