[OpenLayers, Javascript]
In that example we are going to transform latitude and longitude coordinates from epsg:3857 (Google Maps projection) to epsg:4326 (OpenLayers Projection) in just one line.
Substitute longitude and latitudine values to LON and LAT in the code.
point = new OpenLayers.LonLat(LON,LAT).transform('EPSG:4326', 'EPSG:3857');
In point you’ll have an OpenLayers readable point.
