Hi Larry, Check the docs here: http://code.google.com/apis/maps/documentation/javascript/reference.html#spherical
You can change units by specifying the 'radius' parameter from the default. For example, if you want to perform calculations in miles, specify the earth's radius as 3963.19 (only an approximation, of course) computeLength takes Array.<LatLng>, as does computeArea, but the path must be closed. computeArea does not work on a google.maps.Polygon, you'll need to call getPath/getPaths and pass through a single array of LatLngs.
