Psi to Kilopascals
Pounds per square inch is the standard pressure unit for tire inflation and plumbing in the US. A kilopascal is 1,000 pascals, commonly used for tire pressure and weather barometric readings outside the US. 1 psi equals ≈6.89476 kPa, 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
kPa = psi × ≈6.89476
psi = kPa × ≈0.145038
Worked example: 5 psi × ≈6.89476 = ≈34.4738 kPa.

Frequently asked
- How many Kilopascals in a psi?
- 1 psi equals ≈6.89476 kPa.
- How do I convert PSI to Kilopascals?
- Multiply the value in psi by ≈6.89476 to get kPa. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — PSI and Kilopascal 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.
