Please provide values below to convert attopascal [aPa] to bar [bar], or Convert bar to attopascal.




How to Convert Attopascal to Bar

1 aPa = 1e-23 bar

Example: convert 15 aPa to bar:
15 aPa = 15 × 1e-23 bar = 1.5e-22 bar

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.


Bar

The bar is a unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level.

History/Origin

The bar was introduced in 1909 by the British engineering community as a convenient unit for measuring pressure, especially in meteorology and engineering contexts.

Current Use

The bar is widely used in meteorology, engineering, and industrial applications to measure pressure, although the pascal is the SI base unit. It is also common in tire pressure measurements and other pressure-related fields.
