Hi Philippe
In the nightly build, it is possible to have a composer scale bar in km
for maps in degrees. The scalebar however only shows the scale near the
bottom left of the composer map (the scale is not constant in maps in
degrees, as others already noted).
Regards,
Marco

I am the poster of this question and I want to thank all those who
took the time to answer it.
My problem is not trivial for two reasons:
-I work in the Northern Territory (NT), in Australia. The western part
of the NT is in UTM zone 52 and the eastern part in UTM zone 53;
-maps I create often straddle the zone 52/zone 53 boundary and cannot
be in m using our standard projections;
-most baseline GIS work in the Northern Territory is carried out by
the Government in ArcGIS. ArcGIS allows to display a scale bar in km
on a map in degrees and therefore most map users here expect to have a
km scale bar on degrees maps.
I work for a small independent organisation focused on natural
resource management.
I decided that our GIS would be entirely based on freeware.
I chose QGIS as our main GIS software.
As I am often expected to emulate ArcGIS, the scale bar issue matters
to me.
Now I know that QGIS does not offer the km scale bar possibility
offered by ArcGIS.
I will therefore use a work around consisting in creating grids of
suitable mesh size (eg 100 km) in both UTM 52 and UTM 53. I will then
reproject them in DA94 (the Australian standard degrees CRS) and
merge them in GA 94 as a single grid which I will use as a guide to
create (approximate) km scale bars in my GDA94 maps.
