Now from here, how do you convert the PSI into pounds of pressure? I heard from somewhere I think (I dont remember where) that you divide it by two to convert PSI of a punch. That means 700/2= 350 pounds of pressure. Now for Mike Tysons punch I think its 900/2= 450 pounds of pressure.

Now did I do that wrong? If I did the wrong

procedure, how do you convert PSI of a punch into pounds of pressure? Thanks!
