Every time I want to do conversion, I need to get into the console to run proj.4. Is there any online tools for converting coordinates between different EPSG?

Also useful for batch conversions.

this tool is really more handy~! How about including Z-axis conversion? – Harold Chan Feb 21 '13 at 6:05

To do a one-off projection, I usually use the geometry service on our ArcGIS Server's REST endpoint.

You could also use ArcGIS Online's Rest Endpoint, which is available here.

Here is a sample which shows how you can project from 4326 to 3857.
