Parse 'Diving Log' cylinder working pressure

Browse source 
Oh Gods. Why are all other scuba programs so f*&% messed up?

The Diving Log cylinder working pressure is in bar - which is all good.
But their pressure *samples* are in PSI.  Why the h*ll do people mix up
units in the same damn file like that? I despair at the pure
incompetence sometimes.

I suspect the pressure samples aren't "really" in PSI: they are probably
in some user-specified units.
