What is a microbar (µbar)?

A microbar is a pressure unit equal to 10⁻⁶ bar or 0.1 pascal, used for measuring very low pressures.

How is standard atmosphere (atm) defined?

Standard atmosphere is defined as exactly 101,325 pascals, approximating average sea-level atmospheric pressure.

Why convert microbar to standard atmosphere?

Converting microbar to standard atmosphere helps interpret very low pressures on a common atmospheric pressure scale for scientific comparison.
