To convert a measurement in bars to a measurement in millibars, multiply the pressure by the following conversion ratio: 1,000 millibars/bar.

Since one bar is equal to 1,000 millibars, you can use this simple formula to convert:

millibars = bars × 1,000

The pressure in millibars is equal to the pressure in bars multiplied by 1,000.

For example, here's how to convert 5 bars to millibars using the formula above.
millibars = (5 bar × 1,000) = 5,000 mbar

What Is a Bar?

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.

What Is a Millibar?

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 thousandths, or 10-3. Millibars can be abbreviated as mbar; for example, 1 millibar can be written as 1 mbar.
