How to Convert kilopascal to pound per square inch

1 kPa = 0.14503768077999998 psi
1 psi = 6.89476000045014 kPa

To convert kilopascal to pound per square inch, divide the value by 6.89476 (equivalently, multiply by 0.1450376808). To convert pound per square inch back to kilopascal, multiply by 6.89476.

Example: convert 10 kPa to psi:
10 kPa = 10 x 0.14503768077999998 = 1.4503768078 psi

↔ Convert pound per square inch to kilopascal

kilopascal

Definition: The kilopascal (symbol: kPa) is a multiple of the pascal, which is the SI unit of pressure and stress. One kPa is equal to 1000 pascals.

History/origin: Like the pascal, the kilopascal's origin is tied to the development of SI units. It provides a more convenient scale for expressing pressures larger than a single pascal.

Current use: Kilopascals are widely used in engineering, construction, and meteorology for measuring air pressure, fluid pressure, and mechanical stress.

pound per square inch

Definition: Pound per square inch (symbol: psi or lbf/in²) is a unit of pressure in the imperial and US customary systems. It is defined as the pressure resulting from a force of one pound-force applied to an area of one square inch.

History/origin: The pound per square inch is rooted in the English system of units. Its widespread use grew with the development of steam engines and other technologies requiring pressure measurements.

Current use: psi is commonly used in the United States for measuring tire pressure, hydraulic pressure, steam pressure, and the pressure of compressed gases. It's prevalent in automotive, manufacturing, and various engineering applications.
