What is the definition of one bar in pascals?

One bar equals 100,000 pascals, representing force per unit area slightly less than standard atmospheric pressure.

What is a micropascal and where is it commonly used?

A micropascal is one millionth of a pascal and is commonly used to quantify very small pressure changes, especially in acoustic pressure levels.

Why would someone need to convert bar to micropascal?

Converting bar to micropascal helps translate larger industrial and atmospheric pressures into extremely small pressure units useful for sensitive acoustic measurements.
