The atmospheric pressure is the mass of air pressing down on any particular location. At sea level the pressure at standard temperature is :

101.325 kPa.
760mmHg ( also known as torr)
29.92 inHg
14.696 psi
1013.25 millibars (also known as hectopascal)

In physics, pressure is defined as the force per unit area. Atmospheric pressure is due to the weight of the air column per unit area. The air column right from the ground level up to the gravitational limit is taken into consideration. This is theoretical. Practically speaking this pressure will be equal to the pressure exerted by 76 cm of Mercury. This was found by the famous Torricelli's experiment. Hence natural pressure is taken to be 76 cm of mercury.
