Convert microbar to attopascal
Please provide values below to convert microbar [µbar] to attopascal [aPa], or Convert attopascal to microbar.
1 µbar = 1.0000e+17 aPa. To convert microbar to attopascal, multiply the value by 1.0000e+17; to go the other way, divide by it (1 aPa = 1.0000e-17 µbar). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µbar = 1.0000e+17 aPa
- 1 aPa = 1.0000e-17 µbar
- 10 µbar = 1.0000e+18 aPa
- 100 µbar = 1.0000e+19 aPa
How to Convert Microbar to Attopascal
1 µbar = 1e+17 aPa
Example: convert 15 µbar to aPa:
15 µbar = 15 × 1e+17 aPa = 1.5e+18 aPa

Microbar
A microbar (µbar) is a unit of pressure equal to one millionth of a bar, where 1 bar equals 100,000 pascals.
History/Origin
The microbar was introduced as a subunit of the bar to measure very low pressures, particularly in meteorology and vacuum technology, gaining usage in the 20th century as precision pressure measurements became more common.
Current Use
Today, the microbar is used primarily in meteorology for measuring atmospheric pressure variations and in scientific research requiring precise low-pressure measurements.
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.
Frequently Asked Questions
