What is the exact conversion rate from millibar to bar?

1 millibar (mbar) equals 0.001 bar based on standard definitions.

In which fields is converting mbar to bar most useful?

It's especially useful in meteorology, aviation, engineering, and industrial equipment maintenance.

Why might bar not be preferred in some scientific contexts?

Because bar is not an SI base unit, strict scientific applications might choose pascals for pressure measurement.
