What is an exapascal (EPa)?

An exapascal is an SI derived unit of pressure equal to 10^18 pascals, used for extremely large pressures in fields like astrophysics and high-energy physics.

Why is inch mercury measured at 60°F?

The 60°F reference temperature standardizes mercury density to enable consistent calibration and reporting of pressure measurements.

Who uses inch mercury units?

Inch mercury units are commonly used in meteorology for atmospheric pressure, aviation for altimeter settings, and in vacuum systems to indicate vacuum levels.
