The above does not look correct, but I don't have experience with UPS.
Anyway, the proj doc OF-90-284.ps says UPS has the following default
parameters:

k: 0.9994 (scale factor)
lat_0: 0
x_0: 2000000 (meters)
y_0: 2000000 (meters)
lat_0: 90N (north) or 90S (south)
south: ?

Units should be meters AFAIK. So,

unit: meter
units: meters
meters: 1.0


g.setproj appears busted for this projection (can someone confirm?).
