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.

Kilopascal
kPa
Definition
A kilopascal (symbol: kPa) is a unit of pressure equal to 1,000 pascals. It is commonly used for measuring moderate pressures in engineering, meteorology, and industrial applications, providing a practical scale for everyday pressure measurements.
History/Origin
The kilopascal was introduced as a practical unit for measuring pressures commonly encountered in engineering and meteorology. It became widely adopted in the late 20th century for pressure measurements in various industries.
Current Use
Kilopascals are used in meteorology for atmospheric pressure measurements, in engineering for hydraulic and pneumatic systems, in automotive industry for tire pressure, and in construction for structural pressure calculations.
