Difference units of measurement

[pearcetopher]

Hi guys,

when I cross reference my BHN to max psi is this the same thing as cup? is there a difference or a conversion?

why do hogdon manuals list sometimes cup and other times psi?

I thought the CUP was equivilent to PSI - this from ABC handloading By Bill CHevalier page 35:
86234

and from Lee Modern Reloading, 2nd Ed:
86235

There is no direct correlation between CUPs and LUP to psi as measured (and so stated as "PSI" in today's manuals) by peizo-transducers or strain gauges. You might also not get wrapped around the axle over Lee's BHN to psi reference as there is little real correlation there also.
