scalebarUnit - Changing the units

Question

I'm wondering if anyone knows how to alter the units in Javascript API from 'english' (which gives miles) to kilometers?

var scalebar = new esri.dijit.Scalebar({
            map: map,
            scalebarUnit:'english'
          });

I have tried using 'metric'. No luck! Any help on this one?

😮 Doh! Note to self - when re-using code from Esri examples and other places, make sure you don't call stuff twice.

I'd re-used some older code wit a scale bar, but had stripped out the initial definition, so it didn't work, then added the whole lot back in - result 2 bars, one metric the other "american" - Note to Esri, here in England we are trying very hard to use metric 😄

We did that in America back in the 80s. It didn't take.

I tried this myself, however it fails

It has both Yards and meters on it - zooming out, just "english" and zooming in further the two units overwrtite each other.  Snippet where I call it below.        dojo.connect(map, 'onLoad', function(theMap) {
            
   var scalebar = new esri.dijit.Scalebar({
            map: map,
            scalebarUnit:'metric'
          });         
            
            
          //resize the map when the browser resizes
          dojo.connect(dijit.byId('map'), 'resize', map,map.resize);
          
         //add the overview map 
          overviewMapDijit = new esri.dijit.OverviewMap({
              
            map: map,
   expandFactor:4
          }, dojo.byId('overviewMapDiv'));
          overviewMapDijit.startup();
    
        });
