What this conversion means in practice
Kilopascals appear on metric weather charts and many technical PDFs; psi remains the everyday gauge unit in the US. Use this factor when you need to compare a kPa spec to a psi wrench or analog dial.
The exact relationship here is 1 kPa = 0.14503773773 psi, consistent with expressing both units relative to pascals (Pa).
How to convert kilopascal to pound-force per square inch

Kilopascal to Pound-force per square inch FAQ
kPa to psi for weather pressure, duct static pressure, and quick mental checks.
How do I convert kPa to psi?
Multiply the value in kPa by 0.14503773773 to obtain psi. That factor is the ratio of the two units in the same base system as the site’s full converter.
Is this factor the same as the main converter tool?
Yes. The numeric relationship uses the same unit definitions and base normalization as the corresponding converter on CalcRegistry.
Why might my hand calculation differ slightly?
Rounding after intermediate steps, display precision limits, or mixing alternate definitions (for example different “horsepower” variants) can shift the last digits. Use this page’s factor end-to-end for consistency.
