What is the base damage for fists?

I know Khajiit get a bonus from their racial ability:

Claws : Khajiit claws do 15 points of damage.

But what is the regular base damage for fists in Skyrim?


Solution 1:

I believe the base damage for fists is 5.

I derived this but haven't tested it empirically. I have found references to the bonus for Khajiit claws to be both 4x (Strategy Guide and other sites) and +15 (other sites). That leads to this equation x+15=20 and that solves to x=5.
