Hi everyone!

I'm using de Measurement widget and it works great, how ever, I need to measure Distance in Km and Areas in Km2, actually this widget uses Miles an Acres.

I tried looking into the CSS that the widget uses whitout a good result.

David,

You can specify the default unit for area and length measurement. Please see the document at:
http://help.arcgis.com/en/webapi/javascript/arcgis/jsapi/measurement.html
You will find defaultAreaUnit and defaultLengthUnit is configurable.
Hope this helps.

In kilometres:

#add the scale bar
dojo.connect(map, "onLoad", function(theMap) {
       var scalebar = new esri.dijit.Scalebar({
               map: map,
                scalebarUnit: "metric"
       });
});

This will do the job.
