Pressure is 1) an action of a continuous physical force against an object or opposing force (symbol: p or P), and the International Standard (SI) of Units of the pressure is the pascal (Pa), equivalent to one newton per meter squared (N * m^-2); 2) a strong, often threatening influence on an organisation or person.
Reference Definition by Wikipedia: Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure. Various units are used to express pressure (a unit of force divided by a unit of area): the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre; similarly, the pound-force per square inch (psi) is the traditional unit of pressure in the imperial and US customary systems. Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure and the torr is defined as 1/760 of this.
