I'm struggling to understand the coordinate system used by OpenLayers.
Leicester, UK is at approx.
Latitude: 52.63973017532399
Longitude: -1.142578125
But to display the same location using OpenLayers I have to use:
Latitude: 6915601.9146245
Longitude: -125089.1967713
e.g:
var center = new OpenLayers.LonLat(-125089.1967713, 6915601.9146245);
var map = new OpenLayers.Map("demoMap");
map.addLayer(new OpenLayers.Layer.OSM());
map.setCenter(center, 12);
These are clearly not Latitude-Longitude coordinates, is there some conversion I need to take account of?
A working example is http://craig-russell.co.uk/demos/openlayers/so_map.html

It looks like I do need to map between coordinate systems. This is done with the
transform()
function like so:
