Use this page to convert attopascal values into bar, with background details, formulas, a worked example, and a quick conversion table.

1 aPa = 1e-23 bar

1 bar = 100,000,000,000,000,000,000,000 aPa

Example: 35 aPa = 3.5e-22 bar

Attopascal (aPa) is represented in this converter as 1e-18 pascals.

History: Attopascal follows SI prefix conventions for scaling the pascal up or down by powers of ten.

Current use: Attopascal is useful in science, engineering, meteorology, and technical pressure specifications.

Also written as aPa.

A bar equals 100,000 pascals.

History: It was created as a practical pressure unit for engineering.

Current use: Bar is used in compressors, pumps, and diving.

Also written as bar, bars.
