Mike Tyson has a punch pressure of rouhgly 800 pound per square inch (psi)
800 psi = 56.25 kg/cm^2 = 562500 kg/m^2 = 54.44 ATM
SO his punch is equivalent to 54 times the atmospheric pressure.
Let say an average surface area of a fist is 8 inch^2; this will yield a 6,400 pound force, which is equal to 2,903 klogram force, which is 295.9 kg x 9.81 (g).
So 300kg is a good estimation.
