About

kPa to PSI is an online pressure conversion calculator that converts between kilopascals and pounds per square inch. Enter a value in either field and it calculates the equivalent pressure automatically using the formula PSI = kPa × 0.145038 or kPa = PSI × 6.89476. The tool works for tire pressure, air compressors, hydraulic systems, and engineering calculations.

The converter displays results instantly as you type, with options to clear or copy values from either field. A reference table shows common conversions, and the site includes educational content explaining the difference between kPa (metric, used in the UK, Canada, Australia and Europe) and PSI (used in North America and many industries).

Created by Bashar Mal, a civil engineer, the site aims to make pressure unit conversion accessible for automotive work, technical applications and everyday use.

kPa to PSI is a live pressure converter for switching between kilopascals and pounds per square inch. The calculator works bidirectionally: enter a value in either field and it automatically calculates the equivalent pressure using the conversion formulas PSI = kPa × 0.145038 or kPa = PSI × 6.89476. The site includes educational content explaining the difference between the two units, common conversion examples for tire pressure and industrial equipment, and manual calculation formulas if you prefer to do the math yourself. It's designed for automotive, engineering, technical and everyday applications.

Problem: Converting between pressure units manually is time-consuming and error-prone, especially when working with tire pressure, hydraulic systems or engineering specifications.
Solution: Enter a pressure value in either kPa or PSI and the calculator instantly shows the equivalent in the other unit, with copy buttons for easy use.
