Is there a conversion or formula for going to or from one or another?

With reference to the previous link and definition...  No, I do not believe there is a reliable conversion between the two as CUP (copper or lead) is not considered as reliable as a piesoelectric reading of PSI. Most every modern reference to balistic pressures would be as PSI.

Thanks for the info, some of the literature I have on loads is in CUP and some in PSI. Any other info you come up with would be good too.

People often mistakenly write "psi" in place of "pressure"
