I'll repeat: how do they measure it if NOT by pressure?
Bob... pressure AND temperature.
A bit of simple algebra does it for the one-timer, but they have tables of
the pressure they need to make at a given ambient temperature and filling
time (and thus, the presumed heating of the contents during pump-up) to
make the STP volume.
