Convert attopascal to millibar
Please provide values below to convert attopascal [aPa] to millibar [mbar], or Convert millibar to attopascal.
1 aPa = 1.0000e-20 mbar. To convert attopascal to millibar, multiply the value by 1.0000e-20; to go the other way, divide by it (1 mbar = 1.0000e+20 aPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aPa = 1.0000e-20 mbar
- 1 mbar = 1.0000e+20 aPa
- 10 aPa = 1.0000e-19 mbar
- 100 aPa = 1.0000e-18 mbar
How to Convert Attopascal to Millibar
1 aPa = 1e-20 mbar
Example: convert 15 aPa to mbar:
15 aPa = 15 × 1e-20 mbar = 1.5e-19 mbar

Attopascal
The attopascal (aPa) is a unit of pressure equal to 10^-18 pascals, representing an extremely small pressure measurement.
History/Origin
The attopascal was introduced as part of the SI prefixes to denote very small quantities of pressure, but it is rarely used in practical applications due to its minuscule magnitude.
Current Use
The attopascal is primarily used in scientific research and theoretical contexts where extremely small pressure differences are relevant, although it remains largely a conceptual unit.
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.
Frequently Asked Questions
What is 1 attopascal in millibar?
1 attopascal (aPa) = 1.0000e-20 millibar (mbar).
How do you convert attopascal to millibar?
Multiply the attopascal value by 1.0000e-20. For example, 25 aPa × 1.0000e-20 = 2.5000e-19 mbar.
What is 10 attopascal in millibar?
10 aPa = 1.0000e-19 mbar.
Which unit is larger, the attopascal or the millibar?
The millibar is the larger unit: 1 aPa equals only 1.0000e-20 mbar.
