FAQ

Frequently Asked Questions

How do I convert kPa to PSI?

Divide by 6.89476. For example, 220 kPa ÷ 6.89476 ≈ 31.9 psi.

What tyre pressure is 220 kPa in PSI?

About 32 psi, or 2.2 bar — a typical passenger-car front tyre. Placards inside the driver's door often list all three units for exactly this reason.

How many kPa is atmospheric pressure?

Standard atmospheric pressure is 101.325 kPa, which is 14.696 psi or 1,013.25 mbar.

Is kPa gauge or absolute pressure?

It depends on the instrument. A tyre gauge reads gauge pressure — the amount above the surrounding air — so a tyre at 220 kPa gauge holds about 321 kPa absolute. Make sure both sides of a comparison use the same reference.
