Technically speaking, the hectare is not an SI unit, although it is accepted
for use with SI units, along with the litre, tonne (metric ton) and units of
time and angle. The SI unit of area is the square metre.

Subject: [USMA:39149] Pure SI for area in UK?
I noticed in this BBC News science article that only the hectare is used for
area.
It looks like non-SI units for area are either a vanishing breed or gone
altogether:

Perhaps UK readers can confirm.
