The other answer is already helpful, but there is a little adjustment, because the property is named "lng" and not "lon"; (see reference, 2015-04-22): http://leafletjs.com/reference.html#latlng var bngcoords = proj4(bngprojection, [e.latlng.lat, e.latlng.lng]); or, clearer: var latlon = e.latlng; var bngcoords = proj4(bngprojection, [latlon.lat, ...

See my answer to this topic for an example: Using customized Coordinate System for Archaeological site data ...

If those "strange" coordinates do not fit to Gauss-Krueger coordinate systems, they might be similar to the "preu├čisches Koordinatensystem". You will find some links to that in my answer to Conversion of coordinates of "Bochum coordinate system" You have to put up a custom CRS on the point "Trockenberg" in Cassini-Soldner projection, which was ...
