How to Convert Bars to Millibars

Calculators can be used to convert measurements from one unit to another

To convert a bar measurement to a millibar measurement, multiply the pressure by the conversion ratio. One bar is equal to 1,000 millibars, so use this simple formula to convert:

millibars = bars × 1,000

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

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

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


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.


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.

Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
