Probably going to sound stupid

Yeah, this is going to sound like a dumb question but what is the damage formula for melee if you do not have a weapon equipped. Is it calculated by strength and dexterity that you get extra blows or is it just a fixed 1d2 or whatever. Just wondering because I thought it would be really cool if I could create a character that could go up to enemies and just punch them in the face! Could make it like a challenge or something, you know, something like playing the first 1000" with no weapons!
