Standard Pressure* in Various Units

1 atmosphere =

29.92 inches of Hg

760 mm of Hg

14.7 lbs/in²

101325 Pascals (or N/m²) = 101.325 kPa

1.01325 bar

1013.25 mb

                  (The millibar [mb] is the unit most often used by meteorologists.  We shall also use this unit most in our course.)
                 *Recall that the air pressure on campus is about 84 percent of its sea-level value.  Therefore 84% of any of the above
                  numbers would yield the approximate Provo value in those units.
