How to convert kilopascals to pounds per square inch
Car manuals in Canada, Australia and Japan list tyre pressures in kPa, e.g. 230 kPa ≈ 33 psi.
To convert kilopascals to pounds per square inch, use psi = kPa ÷ 6.894757293. One kilopascal equals 0.145038 pounds per square inch, and one pound per square inch equals 6.894757 kilopascals.
Kilopascal (kPa): 1,000 Pa. Pound per square inch (psi): 1 lbf/in² ≈ 6,894.757 Pa.
For the opposite direction, use the PSI to kPa converter. All pressure units are on the pressure converter.

Frequently asked questions
How many pounds per square inch are in a kilopascal?
1 kPa = 0.145038 psi. Multiply kilopascals by 0.1450377377 (or use psi = kPa ÷ 6.894757293).
How do I convert kilopascals to pounds per square inch?
Use psi = kPa ÷ 6.894757293. For example, 1 kPa = 0.145 psi and 10 kPa = 1.4504 psi.
How many psi are in a bar?
1 bar = 14.5038 psi.
Is mmHg the same as torr?
Almost: 1 Torr = 133.3224 Pa and 1 mmHg = 133.3224 Pa differ only in the seventh significant digit. For everyday use they're interchangeable.
