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.
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.
Atmospheric pressure refers to the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. The standard atmosphere (symbol: atm) is a unit of pressure at sea level and is equal to 101325 Pascal.
The 'standard' air pressure is 14 psi.
millibars
higher
The higher the elevation the lower the air pressure. Sea level is considered the standard for air pressure measurement.

It's 1.0002926 with standard pressure.
standard pressure is 760 mm Hg.
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.
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.
