40lbs/ft^2 *((1ft)^2/(12in)^2 = 40 lbs/ft^2 *(1ft^2/144in^2)

write that down on a piece of paper with horizontal division lines. See how the "ft^2" cancels out? You just end up dividing 40 by 144.

With any of these conversion problems, you get it so the units you don't want cancel out. Just divide 40 by 144 and your answer will be in lb/in^2

Fine, here it is. 0.278 lb/in^2.
Can you watch at least one video on how to do these?
