Why is the temperature fixed at 60°F for inch mercury measurements?

The 60°F reference temperature standardizes mercury density, ensuring consistent calibration and reporting of pressures.

Is millipascal suitable for measuring atmospheric pressure directly?

Millipascal units measure very small pressure magnitudes, making them more suitable for precision instruments rather than typical atmospheric pressures.

Can these conversions be used in aviation settings?

Yes, inch mercury is used for altimeter settings and pressure references in U.S. aviation operations, and conversion helps relate these to precise scientific units.
