1 PSI = 6.89476 Kilopascals
How to convert PSI to Kilopascals
To convert PSI to Kilopascals, multiply the value in PSI by 6.89476. For example, 5 psi = 34.4738 kPa.
Going from PSI to Kilopascals means applying a fixed conversion factor: one PSI (psi) is exactly 6.89476 Kilopascals (kPa). 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 PSI and Kilopascals
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 PSI to Kilopascals values
The most frequently searched conversions are 1 PSI = 6.89476 Kilopascals, 5 PSI = 34.4738 Kilopascals, 10 PSI = 68.9476 Kilopascals, and 100 PSI = 689.476 Kilopascals. 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.
