no those are number that have been made up based on the punch a meter in rocky iv. If you think other wise post some credible source. You don't measure force in psi, you measure force in pounds or kj.you measure pressure in psi . If Mr tyson could exert a pressure of 1800 psi on fist area of 6 sq inches, that would mean the force in parted to the target was 6 x1800 which is about 11000 pounds force about the same as a small bomb or indeed the incredible hulkThose are numbers that have been reported. 1800 psi is a lot, but maybe possible in a controlled test...not an actual fight..
If you figure Tyson's fist's striking area is 2 square inches then he is producing roughly 900 pounds of force with his punch.
