Conversion formula

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

Example: 10 mbar × 0.1 = 1 kPa.

About both units

From

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.

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.

Tips & common mistakes

Quick tips

  • 1 mbar = 1 hPa = 100 Pa.
  • Weather reports: "1013 hPa" and "1013 mbar" mean the same thing.
  • Hurricane strength correlates with central pressure drop.

Avoid these

  • Confusing mbar and bar — 1000× difference.
  • Using mbar for industrial pressures — too small.
  • Mixing hPa and mbar in casual writing without noting they are equal.

Frequently asked questions

How many kilopascals in a millibar?
One millibar equals 0.1 kilopascals.
How do I convert millibars to kilopascals?
Multiply the millibar value by 0.1 to get the equivalent in kilopascals.
What is 100 millibars in kilopascals?
100 millibars equals 10 kilopascals.
Is a millibar bigger than a kilopascal?
No. 1 millibar equals 0.1 kilopascals, so one millibar is smaller.
How to convert millibars to kilopascals without a calculator?
Multiply by 0.1 for a quick estimate; use a calculator for precise results.
