Conversion formula

Forward

pascals = millibars × 100

Reverse

millibars = pascals × 0.01

Example: 10 mbar × 100 = 1,000 Pa.

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.

Pascal

The pascal is the SI unit of pressure — one newton per square metre. Named after Blaise Pascal. 1 Pa is a very small pressure; atmospheric pressure is about 101,325 Pa. Pressure readings in engineering are usually in kPa or MPa.

Real-world: Atmospheric pressure: 101,325 Pa. Conversation level: 0.001 Pa sound pressure. Truck tyre: 900,000 Pa.

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 pascals in a millibar?

One millibar equals 100 pascals.

How do I convert millibars to pascals?

Multiply the millibar value by 100 to get the equivalent in pascals.

What is 100 millibars in pascals?

100 millibars equals 10,000 pascals.

Is a millibar bigger than a pascal?

Yes. 1 millibar equals 100 pascals, so one millibar is larger.

How to convert millibars to pascals without a calculator?

Multiply by 100 for a quick estimate; use a calculator for precise results.
