This may be related to the Nissan truck a/c problem.  Pressures 
are in units like bars or millibars or inches of mercury or grams 
per square centimeter or feet of water or atmospheres or pounds 
(or ounces) *per square inch*.

If the answer they're looking for is just "ounces", I have the 
funny feeling the number they're looking for is "ounces of 
refrigerant", not a pressure reading of "ounces per square inch".

This really should be a job for someone who understands a/c --
blowing up a system is really bad news, both monetarily and in 
terms of hospitalization.  At the very least, they 
should talk to the manufacturer's technical representative.

I can show you how to do a conversion from bars to ounces per 
square inch, but from the way this question is formulated, I 
don't think that's what they're looking for, because pressure is 
not mass.
