Converting google map api coordinates into meters

Question

How would I go about converting the results of my map bounding box into meters within javascript?

For example, if I have the coordinates 51.52366625446907, -0.07467269897460938 decimal degrees, can I project that into something like 555000 155000 meters?

(If it is easier, I could try to export my raster from ArcGIS in decimal degree format; I don't know which option would be better).

Answer 1

i would use http://proj4js.org/

Answer 2

You could call the Project Geometries operation on an ArcGIS Geometry Server.
