So here is the code sample i used : var map = new OpenLayers.Map({ div: "map", theme: null, units: 'm', projection: "EPSG:900913", controls: [ new OpenLayers.Control.Navigation({zoomWheelEnabled: false}), new OpenLayers.Control.NavToolbar({zoomWheelEnabled: false}), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.ScaleLine()] }); So you can add the unit you want in this constructor. according to the documentation : http://dev.openlayers.org/releases/OpenLayers-2.6/doc/apidocs/files/OpenLayers/Map-js.html#OpenLayers.Map.units you can specify : ‘degrees’ (or ‘dd’), ‘m’, ‘ft’, ‘km’, ‘mi’, ‘inches’. Enjoy, Best regards. _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
