I'm working in the area of -123, 49.2, all my features are within a 100km radius of that point, but getting xmin, ymin, xmax, ymax looking like: -13703852.48, 6323231.08, -13703717.43, 6323601.12. Trying to print the spatialReference to the console just gives me [object Object] in both Chrome and IE. Can I convert these to my map units?</P></BODY></HTML> Fri, 20 May 2016 16:30:42 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/polygon-getextent-returns-what-units/m-p/280678#M25912 LauraMiles1 2016-05-20T16:30:42Z Re: Polygon getExtent() Returns what Units? https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/polygon-getextent-returns-what-units/m-p/280679#M25913 <HTML><HEAD></HEAD><BODY><P>Laura,</P><P></P><P>&nbsp; If you are using an esri basemap then the maps units are in meters and the maps spatial reference is Web Mercator WKID:102100 / 3857.</P><P></P><P>If you need to convert the extent to Geographic then you need to use <A href="https://developers.arcgis.com/javascript/3/jsapi/esri.geometry.webmercatorutils-amd.html">webMercatorUtils</A> to do so.</P></BODY></HTML> Fri, 20 May 2016 16:40:08 GMT https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/polygon-getextent-returns-what-units/m-p/280679#M25913 RobertScheitlin__GISP 2016-05-20T16:40:08Z
