What is a decipascal?

A decipascal (dPa) is a pressure unit equal to one tenth of a pascal, used for expressing very small pressure magnitudes.

How does a bar compare to standard atmospheric pressure?

A bar is slightly less than standard atmospheric pressure, with 1 atm being approximately 1.01325 bar.

Why convert decipascal to bar?

Converting to bar allows users to represent very small pressures within commonly used industrial or meteorological pressure units.
