Pressure Units and Definitions
- The SI unit of pressure is the pascal (Pa).
- Gauge pressure is the pressure relative to atmospheric pressure.
- In the imperial and US customary systems, the traditional unit of pressure is the pound per square inch (psi).
- Pressure is defined as the perpendicular force per unit area, or force per unit area, typically expressed in units of force per unit area (e.g. N/m² or Pa).
- In a manometer, pressures are expressed in terms of the height of a column of a particular fluid, typically in units of millimeters of mercury (mmHg) or inches of mercury (inHg).
