=20
If your units are meters the formula would be=20
    dblArea =3D pArea.area* 0.0002471
=20
=20

	This is how to use the Field Calculator...
	=20
	Open the feature class "table" while in ArcMap
	Right click "acres" field select calculate values
	In the field calculator dialog box check the advanced tab
	Insert the following code in the Pre-Logic VBA Script Code box
	    Dim dblArea as double
	    Dim pArea as IArea
	    Set pArea =3D [shape]
	    dblArea =3D pArea.area/43560
	Insert the following line in the "FIELD" box
	    dblArea=20
	=20
	Hope this helps....
