Is the bar unit part of the SI system?

No, the bar is not an SI base unit but is widely accepted and used alongside SI units in various fields.

What is the relationship between millibar and hectopascal?

Millibar and hectopascal are numerically equal units of pressure, with 1 mbar equaling 1 hPa.

Why convert bar to millibar?

Converting bar to millibar helps users interpret pressure values in finer scales suitable for meteorological and industrial applications.
