What does an inch of mercury (32°F) represent?

It is a pressure unit defined by the pressure exerted by a one‑inch column of mercury at 32°F under standard gravity.

Why convert inch mercury to pascals?

Because pascals are the SI unit of pressure, converting allows for standardization in scientific, meteorological, and engineering contexts.

Are there limitations to this conversion?

Yes, since inch mercury is temperature and gravity dependent, conversions assume standard conditions which may slightly affect accuracy.
