Study Notes
Pressure Units
- The SI unit of pressure is the Pascal (Pa).
- Gauge pressure is the pressure relative to the surrounding atmospheric pressure.
Traditional Units
- The traditional unit of pressure in the imperial and US customary systems is the pound per square inch (psi).
Manometric Units
- Pressure can be expressed in manometric units such as centimetre of water (cmH2O), where 1 cmH2O is equivalent to approximately 98.06 Pa.
Definition of Pressure
- Pressure is defined as the force per unit area, typically measured in units of force per unit area, such as Pascals (Pa) or pounds per square inch (psi).
