The SI derived unit for pressure is the pascal.
1 pascal is equal to 1.0E+18 attopascal, or 1.0E-5 bar.
Note that rounding errors may occur, so always check the results.

You can do the reverse unit conversion from bar to attopascal, or enter any two units below:
attopascal to micrometer of water
attopascal to microbar
attopascal to zeptobar
attopascal to millibar
attopascal to dyne/square centimeter
attopascal to newton/square meter
attopascal to kip/square inch
attopascal to dekapascal
attopascal to exabar
attopascal to kilopond/square meter
The SI prefix "atto" represents a factor of 10-18, or in exponential notation, 1E-18.
So 1 attopascal = 10-18 pascals.
The definition of a pascal is as follows:
The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.
The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). The word bar is of Greek origin, báros meaning weight. Its official symbol is "bar"; the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars.
