How to convert Kilopascals to PSI
To convert Kilopascals to PSI, multiply the value in Kilopascals by 0.14503768. For example, 5 kPa = 0.7251884 psi.
Going from Kilopascals to PSI means applying a fixed conversion factor: one Kilopascals (kPa) is exactly 0.14503768 PSI (psi). Type any number into the converter above and the equivalent updates instantly, or use the reference table for quick lookups.
Pressure conversions are used in weather forecasting, engineering, diving, automotive maintenance, and industrial processes. Different fields favor different units, making conversion a regular necessity.
Understanding Kilopascals and PSI
The pascal is the SI unit, but it's small, so kilopascals and bars are more practical for everyday use. PSI (pounds per square inch) dominates in US engineering and tire pressures, while atmospheres provide an intuitive reference point — 1 atm is roughly the air pressure at sea level. Weather reports use hectopascals or millibars, which are numerically identical.
How accurate is this conversion?
Pressure conversions are based on fixed physical definitions. One standard atmosphere equals exactly 101,325 pascals, and 1 bar equals exactly 100,000 pascals, so all conversions here are precise.
All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
Quick reference: common Kilopascals to PSI values
The most frequently searched conversions are 1 Kilopascals = 0.14503768 PSI, 5 Kilopascals = 0.7251884 PSI, 10 Kilopascals = 1.4503768 PSI, and 100 Kilopascals = 14.503768 PSI. The full table further down covers every common value, and the calculator handles any number you need in between.
Pro tip: For tire pressure, most vehicles specify PSI in the US and bar or kPa elsewhere. As a rule of thumb, 1 bar ≈ 14.5 PSI, so a typical 2.2 bar tire pressure is about 32 PSI.
