Question

Hello I am using OpenLayers, and I would like make zoom map to show all USA territory
I have added next code to my JS file

zoomMapTo: function (x1, y1, x2, y2) {
    var bounds = new OpenLayers.Bounds(x1, y1, x1, y2);
    map.zoomToExtent(bounds,4);
}

But I don’t know that coordenate should I use
I tring to call it like

zoomMapTo(-19838714.3168264, 2146075.00656018, 19971050.5931969, 11542768.518094);

or

zoomMapTo(-120, 20, -70, 50); 

But I go to some please in ocean
That coordinate I must use ?

Thanks for help.

I find out soulution i need just convert it to EPSG:4326:

var bounds = new OpenLayers.Bounds(); 
bounds.extend(new OpenLayers.LonLat(x1, y1).transform(new OpenLayers.Projection("EPSG:4326"), appOL.mapobj.map.getProjectionObject())); 
bounds.extend(new OpenLayers.LonLat(x2, y2).transform(new OpenLayers.Projection("EPSG:4326"), appOL.mapobj.map.getProjectionObject()
