Pascal is a unit of pressure in the International System of Units, defined as one newton per square meter.
Orders of magnitude (pressure) on Wikipedia provides an overview of pressure measurements and their corresponding orders of magnitude.

Whereas teeth rarely come into contact during normal chewing, grinding of teeth may occur 1-4 hours in a 24-hour period, most often during sleep. The amount of pressure placed on teeth during functional habits is 140–550 kilopascals (20–80 psi), but the pressure can range from 2–20.7 megapascals (290–3,000 psi) during parafunctional habits.
Units of megapascals (MPa) are frequently used for reporting Meyer hardness, but any unit of pressure can be used. [2] The test was originally defined for spherical indenters, but can be applied to any indenter shape. It is often the definition used in nanoindentation testing. [1]
The SI unit of modulus of elasticity (E, or less commonly Y) is the pascal (Pa or N/m²); the practical units are megapascals (MPa or N/mm²) or gigapascals (GPa or kN/mm²). —Preceding unsigned comment added by 77.126.173.47 ( talk ) 16:45, 11 February 2010 (UTC) [ reply ]
Their yield strengths can be anywhere between 250–590 megapascals (36,000–86,000 psi). Because of their higher strength and toughness HSLA steels usually require 25 to 30% more power to form, as compared to carbon steels. [2] Copper, silicon, nickel, chromium, and phosphorus are added to increase corrosion resistance.
A piezophile (from Greek "piezo-" for pressure and "-phile" for loving) is an organism with optimal growth under high hydrostatic pressure, i.e., an organism that has its maximum rate of growth at a hydrostatic pressure equal to or above 10 megapascals (99 atm; 1,500 psi), when tested over all permissible temperatures.
