It's easier to just say how much they can lift to give an approximation, simply because sitting down and doing the math on how fast and hard a character can punch is fucking tedious.Also, speed is super important in how much force your punch carries. If you can't swing your arm fast then you aren't gonna carry any significant force.

Or the technique behind the punch, not to mention any abilities that allows one to amplify their kinetic force.
