Kilopascal

kPa

The kilopascal equals 1000 pascals. Used for tyre pressures in many metric countries, engineering pressures and weather reports. 100 kPa ≈ 1 bar ≈ atmospheric pressure.

Real-world: Tyre pressure: 220–280 kPa. Atmospheric: 101 kPa. HVAC duct static: 0.1–0.3 kPa.

Pound per Square Inch

psi

Pounds per square inch equals approximately 6895 Pa. It is the dominant pressure unit in the US — tyre pressures, plumbing, compressed air. Standard US tyre pressure: 32–35 psi.

Real-world: US tyre: 32–35 psi. Water supply: 40–60 psi. SCUBA tank: 3000 psi. Car AC system: 30–200 psi.

Tips & common mistakes

Quick tips

  • 1 kPa = 1000 Pa = 0.01 bar = 0.145 psi.
  • 100 kPa ≈ 1 bar.
  • Commonly used on tyre manuals in Commonwealth countries.

Avoid these

  • Confusing kPa with kW or kJ.
  • Using kPa when bar would be simpler.
  • Mixing absolute and gauge in kPa without specification.

Frequently asked questions

How many psi in a kilopascal?
One kilopascal equals 0.145 psi.
How do I convert kilopascals to psi?
Multiply the kilopascal value by 0.145 to get the equivalent in psi.
What is 100 kilopascals in psi?
100 kilopascals equals 14.5038 psi.
Is a kilopascal bigger than a pound per square inch?
No. 1 kilopascal equals 0.145 psi, so one kilopascal is smaller.
How to convert kilopascals to psi without a calculator?
Multiply by 0.15 for a quick estimate; use a calculator for precise results.
