    I haved looked for a similar formula without success so will be interested in any input you get. Have you heard that such a thing exists? One guy very knowledgable in ballistics told me that "50,000 CUP was close to the same as 60,000 to 65,000 PSI". That wasn't much help obviously but better than nothing I suppose.
