How to convert kilopascals to pounds per square inch

1 kPa ≈ 0.145038 psi

1 kPa = 1,000 Pa exactly and 1 psi ≈ 6,894.757 Pa (NIST SP 811), so 1 kPa ≈ 0.1450377 psi. Handbook 44 lists 0.145 037 744.

Examples

  • 101.325 kPa = 14.695949 psi: one standard atmosphere (NIST)
  • 220 kPa = 31.908302 psi: a tire pressure printed in kPa
  • 200 kPa = 29.007548 psi: a reading on a metric pressure gauge

Common mistakes

  • Converting keeps the reference point: a gauge reading in kPa becomes a gauge reading in psi, and an absolute one stays absolute.
  • Don’t mix up kPa with kgf/cm². 1 kgf/cm² is 98.0665 kPa exactly, about 14.22 psi.

Frequently asked questions

How many psi is 1 kPa?

1 kPa is about 0.145 psi. Multiply kPa by 0.145038, or divide by 6.895; 200 kPa is about 29.0 psi.

What is 220 kPa in psi?

220 kPa is about 31.9 psi. Since 220 kPa is also 2.2 bar, you get the same answer converting 2.2 bar.

What is atmospheric pressure in psi?

One standard atmosphere, 101.325 kPa exactly, is about 14.696 psi. It is a defined reference value, not a live weather reading.

Why do some charts say 1 kPa = 0.145 psi?

They round 0.1450377 to three figures. The effect is small: at 250 kPa it gives 36.25 psi against the more precise 36.26 psi.
