Frequently Asked Questions
How do you convert kPa to PSI?
Multiply by 0.145038. So 1 kPa = 0.145038 PSI, and 10 kPa = 1.4504 PSI. This conversion factor is exact (or rounded to 3 decimals for practical use).
Where does the 0.145038 come from?
It's the standard SI/US-customary conversion factor for kPa → PSI, defined by NIST and BIPM. The CalcIntel Kilopascals to PSI uses the same factor your physics textbook, government conversion table, and Wolfram Alpha would use.
How accurate is this conversion?
Mathematically exact. The only loss of precision comes from rounding the displayed result to 3 decimals. For scientific applications requiring more precision, multiply by the factor manually.
Can I convert in the other direction?
Yes — divide by 0.145038 to convert from PSI back to kPa, or use the CalcIntel PSI-to-kPa calculator if available.
