The SI derived unit for pressure is the pascal.
1 pascal is equal to 1.0E+18 attopascal, or 0.01 millibar.
Note that rounding errors may occur, so always check the results.

You can do the reverse unit conversion from millibar to attopascal, or enter any two units below:
attopascal to kip/square inch
attopascal to micropascal
attopascal to micron mercury
attopascal to gigabar
attopascal to centibar
attopascal to kilogram/square centimeter
attopascal to millitorr
attopascal to millimeter water
attopascal to centimeter water
attopascal to dyne/square centimeter
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.
A millibar (mb) is 1/1000th of a bar, a unit for measurement of pressure. It is not an SI unit of measure, however it is one of the units used in meteorology when describing atmospheric pressure. The SI unit is the pascal (Pa), with 1 millibar = 100 pascals (a hectopascal)
