Pressure (symbol: P) is the force per unit area applied in a direction perpendicular to the surface of an object. Gauge pressure is the pressure relative to the local atmospheric or ambient pressure.
Pressure is an effect which occurs when a force is applied on a surface. Pressure is the amount of force acting on a unit area. The symbol of pressure is P.

where:
Pressure is a tensor quantity, and has SI units of pascal; 1 Pa = 1 N/m, and has EES units of psi; 1 psi = 1 lb/in.
Pressure is transmitted to solid boundaries or across arbitrary sections of fluid normal to these boundaries or sections at every point. It is a fundamental parameter in thermodynamics and it is conjugate to volume.
The SI unit for pressure is the pascal (Pa), equal to one newton per square meter (N/m or kg/m·s). This special name for the unit was added in 1971; before that, pressure in SI was expressed simply as N/m.
Non-SI measures such as pound per square inch (psi) and bar are used in parts of...
