Area of a Polygon, is the projection taken into account

I have this bit of code...

public static bool Area(IFeatureSet input)

            // We add the area field
            string fieldname = AddField(input, "Area");
            // we add all the old features to output
            foreach (IFeature feature in input.Features)
                IMultiPolygon polygon = MultiPolygon.FromBasicGeometry(feature.BasicGeometry);
                feature.DataRow[fieldname] = polygon.Area;

            return true;
Just wondering what are the units that are returned by polygon.Area.
My Polygon data is in Lan/Long coordinates, so does Area return an Area that takes earth curvature into account.
Can I specify the units to return? (say Acres?)

Did you ever get an answer to this? I have the same question.
