Air pressure can be stated in different ways. kpa is kilopascals, the metric system psi is pounds per square inch in the standard system 1 bar is equal to the air pressure at sea level 1 kpa= about 7 psi 15 psi = about 1 bar
Standard air pressure at sea level is 1 atmosphere, or 1 atm. This is the adopted standard atmosphere value, but sea level pressure will not always equal to this value due to changes in weather. 1 atm = 101 325 pascals = 1.01325 bars.
The volume of 1 pound of air can vary depending on the temperature, pressure, and density of the air. At standard temperature and pressure (STP) conditions of 0 degrees Celsius and 1 atmosphere pressure, the volume of 1 pound of air is approximately 13.1 cubic feet. However, if the air is at a different temperature or pressure, you would need to use the ideal gas law equation (PV = nRT) to calculate the volume.
There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.
The standard value for air pressure at sea level is around 1013.25 millibars, or 29.92 inches of mercury (inHg).

Air at STP refers to air that is at a standard temperature of 0 degrees Celsius and a standard pressure of 1 atmosphere (101.3 kPa). This standard condition is often used for comparing and measuring gas properties.

The average air pressure at sea level is about 1013.25 millibars, or 14.7 pounds per square inch (psi). This pressure is known as standard atmospheric pressure.
air pressure is the firce exerted by moving air moleculesAir pressure is the air around you. Air pressure can pushing every where so the air from the top only dosent squish you into a pancake. Pressure is defined as force per unit area. The standard unit for pressure is the Pascal, which is a Newton per square meter.
Standard temperature and pressure (STP) is a temperature 0ºC (32ºF) with the air pressure the same as at sea level.
