How many kilopascals is 1 PSI?

1 PSI equals exactly 6.894757 kPa. This comes from the definition: 1 psi = 1 lbf/in² = 4.44822 N / (0.0254 m)² = 6,894.757 Pa = 6.894757 kPa.

How many PSI is 1 kPa?

1 kPa equals approximately 0.14504 PSI. This is the inverse of the standard 6.894757 factor.

What is a typical tire pressure in kPa?

Most passenger car tires are inflated to 30–35 PSI, which is about 207–241 kPa. Many vehicles sold in metric countries display tire pressure in kPa on the door jamb label.

What is the difference between PSI and kPa?

PSI (pounds per square inch) is an imperial unit commonly used in the US. kPa (kilopascal) is the metric (SI) unit used internationally. 1 kPa = 1,000 Pa, and 1 Pa = 1 N/m². For most everyday pressures, kPa values are about 7 times larger than the same pressure in PSI.

Is this absolute or gauge pressure?

The conversion factor is the same for both absolute (psia, kPa abs) and gauge (psig, kPa g) pressure. The mathematical ratio between PSI and kPa does not change based on reference point — only the value you start with differs.

Can I convert kPa back to PSI with this tool?

Yes. Use the reverse input field in the tool: enter a kPa value and it instantly shows the PSI equivalent using the factor 1 kPa = 0.14504 PSI.
