Convert Standard atmosphere to millibar
Please provide values below to convert Standard atmosphere [atm] to millibar [mbar], or Convert millibar to Standard atmosphere.
1 atm = 1013.25 mbar. To convert Standard atmosphere to millibar, multiply the value by 1013.25; to go the other way, divide by it (1 mbar = 0.000986923266716 atm). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 atm = 1013.25 mbar
- 1 mbar = 0.000986923266716 atm
- 10 atm = 10132.5 mbar
- 100 atm = 101325 mbar
How to Convert Standard Atmosphere to Millibar
1 atm = 1013.25 mbar
Example: convert 15 atm to mbar:
15 atm = 15 × 1013.25 mbar = 15198.75 mbar

Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
Millibar
A millibar (mbar) is a unit of pressure measurement equal to one-thousandth of a bar, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The millibar was introduced in the early 20th century as a convenient unit for meteorological measurements, replacing the bar in many applications due to its smaller size. It became widely adopted in weather reporting and atmospheric studies.
Current Use
Today, the millibar is still used in meteorology and atmospheric sciences to report atmospheric pressure, although it is gradually being replaced by the Pascal (Pa) in scientific contexts. It remains a standard unit in weather forecasts and reports.
