Kilopascal

kPa

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

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

Millimeter of Mercury

mmHg

The millimetre of mercury equals about 133.3 Pa โ€” the pressure exerted by a 1 mm column of mercury at 0 ยฐC under standard gravity. Traditionally and still used in medicine: blood pressure of 120/80 mmHg.

Real-world: Normal blood pressure: 120/80 mmHg. Atmospheric: 760 mmHg. Good vacuum: <1 mmHg.

Tips & common mistakes

Quick tips

  • 1 kPa = 1000 Pa = 0.01 bar = 0.145 psi.
  • 100 kPa โ‰ˆ 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.
