How to Convert Millibars to Bars

conversion scale showing millibars and equivalent bars pressure values

To convert a millibar measurement to a bar measurement, multiply the pressure by the conversion ratio. One millibar is equal to 0.001 bars, so use this simple formula to convert:

bars = millibars × 0.001

The pressure in bars is equal to the millibars multiplied by 0.001.

For example, here's how to convert 5 millibars to bars using the formula above.
5 mbar = (5 × 0.001) = 0.005 bar

Millibars and bars are both units used to measure pressure. Keep reading to learn more about each unit of measure.

Millibars

One millibar is equal to one-thousandth of a bar, which is defined as the pressure of one newton per square meter. One millibar is also equal to one hectopascal.

The millibar is a non-SI metric unit for pressure. In the metric system, "milli" is the prefix for 10-3. Millibars can be abbreviated as mbar, for example 1 millibar can be written as 1 mbar.

Bars

The bar is equal to 100,000 pascals, which are defined as the pressure of one newton per square meter. One bar is just less than the average atmospheric pressure.

The bar is a non-SI metric unit for pressure. Bars can be abbreviated as bar, for example 1 bar can be written as 1 bar.
