vacuum figure of merit = volume / number of fermions in the volume
You decide what figure of merit represents a vacuum.
If a vacuum figure of merit is above your standard
in some region of interest,
you have a unit vacuum in that region.
If it's twice as high, you have a double vacuum.
If it's half as high, you have half a vacuum.
A vacuum must be measured against a vacuum standard,
just as distance must be measured against a distance standard,
and a time must be measured against a time standard.
A similar figure of merit exists for the number of bosons in a volume,
and thermometers provide an approximation.
