What does inch mercury (32°F) measure?

It measures pressure as the force exerted by a one-inch column of mercury at 32°F under standard gravity.

Why use decipascal for pressure measurements?

Decipascal is used for expressing very small pressure magnitudes with fine resolution, useful in acoustic and laboratory settings.

Is this conversion applicable worldwide?

Inch mercury is mainly used in the US, so conversion needs may vary internationally; decipascal is an SI unit used globally for small pressures.
