What is millibar used for?

Millibar is commonly used in meteorology and atmospheric sciences to express air pressure, including sea-level and surface atmospheric pressure on weather maps and forecasts.

Where is inch mercury (32°F) commonly applied?

Inch mercury (32°F) is used for atmospheric and altimeter pressure reporting in meteorology and aviation, as well as indicating vacuum levels in HVAC, refrigeration, and automotive diagnostics.

Why might this conversion be important for aviation?

Converting from millibar to inch mercury allows pilots and meteorologists to interpret and calibrate altimeter settings consistently, especially when transitioning between international and US measurement standards.
