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.
The pascal (Pa) is the standard unit of pressure.
The 'standard' air pressure is 14 psi.
The standard atmosphere is a unit of pressure and is defined as being equal to 101.325 kPa. Pressure is the force F per unit area A applied to an object in a direction perpendicular to the surface. p = F / A.
The SI unit for pressure is a Pascal but in this case the standard unit is the standard atmosphere (= 101325 Pa).
No. A Newton is a unit of force, while pressure is force per unit area. The standard unit of pressure is a Pascal, which is also a derived SI unit.
No. A Newton is a unit of force, while pressure is force per unit area. The standard unit of pressure is a Pascal, which is also a derived SI unit.
In weather maps, atmospheric pressure is measured in millibars. Standard atmospheric pressure is 1013.2 millibars at sea level. Air pressure varies depending on temperature and air density.

The international standard unit for measuring pressure is the pascal. 1 pascal = 1 newton / square meter. A unit commonly used is the bar; 1 bar = 100,000 pascal; and that's the approximate air pressure at sea level. Older units that are still sometimes used include mmHg (millimeter mercury).
Pressure is defined as the force per unit area applied in a direction perpendicular to the surface. The standard unit of pressure is the pascal (Pa). This did not answer my question on how pressure is used.
