Equivalent pressure

Your value shown in PSI, kilopascals, bar and atmospheres.

How to convert PSI to kPa

PSI (pounds per square inch) is the everyday US pressure unit, while the kilopascal (kPa) is the SI metric unit used on many tire placards, spec sheets and TPMS displays. Because 1 PSI is defined in pascals, the conversion is a single fixed factor.

kPa = PSI × 6.89476
PSI = kPa ÷ 6.89476 (kPa × 0.145038)

Worked example

Your tire placard lists 32 PSI. Multiply by 6.89476: 32 × 6.89476 = 220.6 kPa, which is what a metric TPMS gauge would display.

Quick reference

Handy anchors: 100 kPa ≈ 14.5 PSI (and exactly 1 bar), while 200 kPa ≈ 29 PSI. Most passenger-car tires sit between 210 and 250 kPa (30–36 PSI).

Frequently asked questions

How many kPa is 1 PSI?

About 6.89476 kPa. To convert PSI to kPa, multiply by 6.89476.

How do I convert PSI to kPa?

Multiply the PSI value by 6.89476. For example, 32 PSI × 6.89476 = 220.6 kPa.

What is 32 PSI in kPa?

32 PSI, a typical car tire pressure, equals about 220.6 kPa.

How do I convert kPa to PSI?

Divide the kPa value by 6.89476 (or multiply by 0.145038). For example, 100 kPa ÷ 6.89476 = 14.5 PSI.

What is 100 kPa in PSI?

About 14.5 PSI, which is also exactly 1 bar.

Why do some cars show tire pressure in kPa?

Kilopascals are the SI metric unit, so many manufacturers print kPa on the tire placard and TPMS display alongside or instead of PSI.
