What is a kilopascal?

The engineering and tyre-pressure unit — 1 kPa = 1000 Pa

Definition

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

Common uses

  • Tyre pressures in Canada, Australia
  • Engineering pressure specs
  • Weather pressure in some contexts

🌍 Real-world scale

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

Tips

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

Common mistakes

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