What is an inch mercury (32°F) unit?

It is a manometric pressure unit defined as the pressure from a one-inch column of mercury at 32°F under standard gravity.

Why convert inch mercury to newton per square meter?

Converting to newton per square meter expresses pressure in SI units, allowing compatibility with international standards and scientific applications.

Does temperature affect the conversion?

Yes, since inch mercury is defined at 32°F, temperature deviations can slightly affect the pressure equivalence.
