How to Convert Atmospheres to Millibars
To convert a measurement in atmospheres to a measurement in millibars, multiply the pressure by the following conversion ratio: 1,013.25 millibars/atmosphere.
Since one atmosphere is equal to 1,013.25 millibars, you can use this simple formula to convert:
The pressure in millibars is equal to the pressure in atmospheres multiplied by 1,013.25.
Atmospheres and millibars are both units used to measure pressure. Keep reading to learn more about each unit of measure.
What is an Atmosphere?
The atmosphere is a reference measure of pressure equal to 101,325 pascals or 1,013,250 dynes. The atmosphere was originally defined as the pressure of 760 millimeters of mercury at standard gravity at 0 °C, but was later redefined in 1954 to be equal to 1,013,250 dynes.
Atmospheres can be abbreviated as atm; for example, 1 atmosphere can be written as 1 atm.

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.
