Convert Millibars to Atmospheres
Enter the pressure in millibars below to get the value converted to atmospheres.
How to Convert Millibars to Atmospheres
To convert a millibar measurement to a atmosphere measurement, multiply the pressure by the conversion ratio. One millibar is equal to 0.000987 atmospheres, so use this simple formula to convert:
The pressure in atmospheres is equal to the millibars multiplied by 0.000987.
Millibars and atmospheres are both units used to measure pressure. Keep reading to learn more about each unit of measure.
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.
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.

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.
