Detailed Description

A physical pressure value, which can be instantiated, and then expressed, in different commonly used pressure units (kPa, mbar, torr, atm, and more).

Within SuperNOVAS it is normally used to express atmospheric pressure at an observing location, but users may utilize it in any other context also.
