Kilopascals to Psi
A kilopascal is 1,000 pascals, commonly used for tire pressure and weather barometric readings outside the US. Pounds per square inch is the standard pressure unit for tire inflation and plumbing in the US. 1 kPa equals ≈0.145038 psi, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to pressure, measured here against pressure's base unit (Pa) — every other pressure unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
psi = kPa × ≈0.145038
kPa = psi × ≈6.89476
Worked example: 5 kPa × ≈0.145038 = ≈0.725189 psi.

Frequently asked
- How many PSI in a kilopascal?
- 1 kPa equals ≈0.145038 psi.
- How do I convert Kilopascals to PSI?
- Multiply the value in kPa by ≈0.145038 to get psi. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Kilopascal and PSI are both defined by a fixed conversion factor to pressure's base unit (Pa), so the result shown is exact to the precision displayed, not an approximation.
