Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. It is a fundamental concept in physics and engineering, used to describe the state of gases and liquids.

The most common units of pressure are the pascal (Pa) in the SI system, the bar (used in Europe and industry), and pounds per square inch (PSI) in the imperial system. Other units include atmosphere (atm), torr, and millimeters of mercury (mmHg).
