I converted some raster data to polygon(s) because I want to calcluate acreage of the extent of this layer. All I had was a jpg (raster) which I converted to polygons (Conversion Tools> Raster to Polygon) I added a fieldl and tried to caclulate acreage but it looks like it just calculated each of the 316707 pixels @ 2.61 acres. Does this seem correct if I summarized the Acres field?
