A microbar (µbar) is a unit of pressure equal to one-millionth of a bar, used for measuring very small pressures such as in vacuum systems and sensitive atmospheric studies.

Why convert microbar to bar?

Converting from microbar to bar helps compare very small pressure measurements with the more common industrial and meteorological pressure unit, facilitating better data interpretation.

Is the bar an SI unit?

The bar is not an SI base unit but is accepted for use with the SI and is widely employed in meteorology, engineering, and industry.
