What does one inch mercury (32°F) represent in terms of pressure?

One inch mercury (32°F) is the pressure exerted by a one-inch column of mercury at 32°F under standard gravity, approximately equal to 3386.39 pascals.

Why is the petapascal unit used?

Petapascal is used to represent extremely large pressures, such as those in high-energy-density physics, astrophysics, and shock-physics research.

Can I use this conversion for everyday pressure measurements?

Since petapascal values represent extremely large pressures, typical everyday measurements in inch mercury convert to very small numbers in petapascal and may not be practical.
