Repost: What are the units of Reid Vapor Pressure (RVP)?

What are the units of RVP?
Regardless of the pressure dimensions specified, Reid Vapor Pressure (RVP) will come out in PSI, not PSIA or PSIG, because it is a differential pressure.

Note: This is not consistent with D323-82 which indicates the final pressure should be absolute. Prior versions were analyzed as differential pressure and we decided to continue the older RVP reporting methods.

About PRO/II: PRO/II is the major product in the Process Engineering Suite (PES). This process simulation software optimizes plant performance by improving process design, operational analysis, and performing engineering studies. It is designed to perform rigorous heat and material balance calculations for a wide range of chemical processes. PRO/II allows users to evaluate the use of heat integration with case studies, rigorously evaluate process improvements with the help of a process flow diagram (PFD), or model crude distillation units. PRO/II offers a wide variety of thermodynamic models to virtually every industry and is incredibly cost effective, decreasing both capital and operating costs.
