The measure of the force due to air pressing on a surface is called the force.If you divide that by the area of the surface, then you have the pressure.
You're looking for "air pressure", but you haven't described it correctly.The pressure is not the force pushing on the surface.It's the (force pushing on the surface) divided by the (area of the surface).
Air pressure is the measure of the force with which air molecules push on a surface.
Air consists of gaseous molecules which are always in random motion when they collide with a solid or liquid surface they apply a force to push the surface this force for per unit area is known as pressure, the gravitational force on gaseous molecules (in bulk) is also responsible for atmospheric pressure.
What is normally used here is not a force, but a force per unit area; this is called pressure. The SI unit for pressure is the pascal.
The measure of the force exerted by air molecules on a surface per unit area is air pressure.

That is usually described in units of pressure - force per unit area. The SI unit for pressure is the pascal, equivalent to newton/meter2.
We use force to push an object. The SI unit of force is Newton. Newton is the force which can move a body of mass 1 kg with a speed of 1m/s.
