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).
