Could somebody give me a formula to convert Pascals to PSI? I understand that you probably have to convert Pounds of Force to Newtons. But where do I go from there?

This ought to be in physics.SE. Anyway, typing pascal to PSI in Google nets you the conversion factor. –  J. M. Sep 15 '11 at 19:46

According to Wikipedia, a pound-force is 4.4482216152605 N exactly. An inch is by definition 0.0254 meters exactly, so $$1\,\text{PSI} = \frac{4.4482216152605\,\mathrm N}{(0.0254\,\mathrm m)^2} \approx 6894.75729\,\mathrm{Pa}$$ or $$1 = 6894.75729 \frac{\mathrm{Pa}}{\mathrm{PSI}}$$ Divide your pascal magnitude by this unity, and you will get the same magnitude expressed in PSI.
