Conversion formula

Forward
millibars = kilopascals × 10
Reverse
kilopascals = millibars × 0.1

Example: 10 kPa × 10 = 100 mbar.

About both units

From

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.

To

Millibar

mbar

The millibar equals 100 pascals or 1/1000 bar. It is the traditional unit for atmospheric pressure in meteorology (now called hectopascal, hPa, but numerically identical). Sea-level pressure averages 1013 mbar.

Real-world: Sea-level average: 1013 mbar. Deep low-pressure storm: below 980 mbar. Hurricane eye: below 920 mbar.

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 millibars in a kilopascal?
One kilopascal equals 10 millibars.
How do I convert kilopascals to millibars?
Multiply the kilopascal value by 10 to get the equivalent in millibars.
What is 100 kilopascals in millibars?
100 kilopascals equals 1,000 millibars.
Is a kilopascal bigger than a millibar?
Yes. 1 kilopascal equals 10 millibars, so one kilopascal is larger.
How to convert kilopascals to millibars without a calculator?
Multiply by 10 for a quick estimate; use a calculator for precise results.
