PSI
psi
Definition
Pounds per square inch (symbol: psi) is a unit of pressure in the imperial system, representing the pressure resulting from a force of one pound-force applied to an area of one square inch. It equals approximately 6,895 pascals.
History/Origin
PSI was developed in the British imperial system for measuring pressure in mechanical and hydraulic systems. It became widely used in the United States and remains the standard unit for many pressure measurements in American industry.
Current Use
PSI is used extensively in the United States for tire pressure, hydraulic systems, pneumatic tools, industrial pressure measurements, automotive applications, and mechanical engineering specifications.
