In vibration when converting from say displacement readings to velocity readings, it is necessary to multiply by (2*pi*f) where f is the frequency expressed in Hz. Using what you've discovered, could we introduce a conversion that uses the entry in the Y register (or some other memory location) as part of the conversion?

displacement*(2*pi*f) = velocity
velocity*(2*pi*f) = acceleration
displacement*(2*pi*f)^2 = acceleration
and of course their inverses.


I know that this is a very simple program, but it would be nice if the conversion utility handled it natively; and possibly an interesting exercise.

Any other realms where this would be useful?

Perhaps I'm not understanding your question correctly?
I think we are talking about different calculators. This discussion is for RPL calcs (48/49/50). In these calcs there's no Y register, and as long as you put proper units to your variables, everything should work:
displacement[mm]*(2*pi*f[Hz]) = mm*Hz=mm*(1/s)=mm/s
So your units of velocity would be correct. Similar thing for the other cases.
