g.proj outputs whatever is in the PROJ_UNITS file. The textual
description of the unit can be whatever the user chooses it to be, or
in the case of "g.proj -c", whatever is obtained from the source
specified by georef=. GRASS itself only the unit/units fields for
display to the user; calculations use the numeric value in the meters
field.
What do your scripts use the "unit" or "units" field for?
