[Qgis-user] How Do I Set Field Calculator Units For Area

[Alister Hood]

Hi there,
I *think* the area calculations are always in the unit for the layer's
CRS.  So you could either:
- find out what this unit is, and convert the areas to square feet by
multiplying by the correct factor, or
- convert the layer to a CRS which uses square feet.
N.B. there is a feature request to enable coordinate conversion in the
field calculator (although I didn't mention that it would be useful also
for area and length calculations).  See http://hub.qgis.org/issues/4078
