What is a millibar (mbar)?

A millibar (mbar) is a metric unit used to measure atmospheric pressure.

It's most commonly used in weather forecasting and reporting.

(Technically, one millibar is equal to 0.1 kilopascal, or kPa).

The Role of Millibars in Weather Forecasting

Meteorologists use millibars as the primary unit to measure and report atmospheric pressure.

On weather maps, you'll see lines called isobars, which connect areas of equal pressure, drawn in millibar intervals.

Standard atmospheric pressure at sea level is about 1013 mbar.

This number is a key benchmark for weather conditions:

High-Pressure System (Anticyclone): Generally above 1013 mbar, associated with clear skies and calm weather.
Low-Pressure System (Cyclone): Generally below 1013 mbar, often bringing clouds, wind, and storms.

Are Millibars and Hectopascals (hPa) the Same?

Yes, for all practical purposes, a millibar (mbar) and a hectopascal (hPa) are the same.

The two units are used interchangeably.

The conversion is simple: 1 mbar = 1 hPa.

While you'll still see millibars in public weather reports (especially in the U.S.), the hectopascal is the preferred SI (International System of Units) unit for global scientific consistency.

How to Read Barometric Pressure in Millibars

A barometer measures barometric pressure—the weight of the air above you—using millibars.

Watching the change in this reading is key to predicting the weather:

A falling barometer (decreasing mbar value) suggests a low-pressure system is approaching, bringing a higher chance of rain or storms.
A rising barometer (increasing mbar value) typically signals a high-pressure system is moving in, meaning improving or fair weather.
