Pressure definition: the exertion of force upon a surface by an object, fluid, etc., in contact with it. See examples of PRESSURE used in a sentence.
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer ), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. [2]
Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area. The basic formula for pressure is F/A (Force per unit area). Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, and Gauge Pressure.

Fluid Pressure; Hydrostatic Pressure; Factors Affecting Pressure. Since the pressure is dependent on the area over which the force is acting, the pressure can be increased and decreased without any change in the force. The force applied to be constant if the surface becomes smaller the pressure increases and vice versa.
2 days ago · Barometric pressure is the pressure within the Earth's atmosphere. It measures the force that the atmosphere exerts per unit area. Another name for barometric pressure is atmospheric pressure. Barometric pressure heavily depends on weather conditions and altitude. At Earth's surface, it varies between 940-1040 hPa, or 13.6-15.1 psi.
Fluid pressure has no direction, being a scalar quantity. The forces due to pressure have well-defined directions: they are always exerted perpendicular to any surface. (See the tire in Figure 11.6, for example.) Finally, note that pressure is exerted on all surfaces. Swimmers, as well as the tire, feel pressure on all sides. (See Figure 11.7.)
