At sea level, the approximate value of atmospheric pressure in those units of measure is as follows: 1  101.3 kPa which is how it is usually expressed. 2  In pascals, it is 101325 pascals.lthough 1013.25 mb (760 mm Hg) is considered to be the standard atmospheric pressure at sea level, it does not mean that the pressure at this level has this value, actually this being 1011 mb.
