Short description: none
This article is about static pressure. For sound pressure see orders of magnitude (sound pressure)

This is a tabulated listing of the orders of magnitude in relation to pressure expressed in pascals. psi values, prefixed with + and -, denote values relative to Earth's sea level standard atmospheric pressure (psig); otherwise, psia is assumed.

Actual impact pressure depends on strike to bone, soft tissue, padded surface, or brick wall. Also depends upon deflection or resistance of object struck. Heavyweight boxing champions have been shown to strike with over 1,000 pounds-force (4,400 N) of force, which would imply ~170 psi (> 1100 kPa) over same area.
