What does inch mercury (32°F) measure?

It measures pressure exerted by a one-inch column of mercury at 32°F under standard gravity, often used in meteorology and HVAC.

Why use millipascal as a pressure unit?

Millipascal is useful for representing very small pressure magnitudes, important in precision instruments like microfluidics and acoustic sensors.

Is this conversion suitable for everyday pressure readings?

Due to the very large values generated, millipascal units may not be practical for common atmospheric or vacuum pressures without proper scaling.
