Scale is a ratio, for example: 1 inch = 24000 inches -or- 1/24000 -or- 1 ft. = 24000 feet

In other words 1:7M what? Or is it unit-less since it's a ratio? Sorry if that's a dumb question. * Next, when you manually specify the resolutions of the map (i.e. map.resolutions = [...,...,...];), what units are those? I checked the map in the DOM inspector and it says the units are 'degrees', does that mean decimal degrees? * Also if this or anything related to scale, resolution or Geo-spatial accuracy in general is documented anywhere for OpenLayers, can someone point me in that direction?
