area - How to recalc WGS84 Shape_Area field to square miles in ArcGIS 10


What are the units of the Shape_Area field in a wgs84 feature class? Is it decimal degree squared? I would like to convert that to something more meaningful like square miles without reprojecting the feature class... Is there a formula for it out there? I am looking to recalc the field programmatically. Thanks for your help!
