[Qgis-user] Calculating acreage in 2.2

[Randal Hale]

I think I may have found a bug....or I'm just slightly confused.

I'm working on a client job (digitizing forestry stands) and I need to 
calculate acres of the final area. The data I'm working with is in 
EPSG:2274. So I create a field that is decimal (width 20, precision 5) 
and in the field calculator I use $area/43560 - (there are 43560 square 
feet in an acre). My result is one decimal off - instead of 195.30 acres 
I have 19.53 Acres. I've done this enough to where I'm questioning every 
button push. If I divide by 4356 I get the correct number. I'm currently 
doing this in Windows 7 OSGEO install QGIS 2.2.

Anyway - can someone tell me I'm crazy...or not crazy. Projections are 
set correctly...cat has remained off the keyboard etc.

Randy
