Coordinate System Converter
Convert map coordinates between WGS84, Web Mercator, UTM and Canada Lambert. Check the converted points on a map.
How do I convert easting and northing into longitude and latitude?
Upload a CSV with x and y columns, choose its coordinate system and select the output system. For UTM, specify the zone and hemisphere. The output includes transformed coordinates, a geographic map preview and a numerical round-trip check. Definitions run locally; vertical transformations and datum grid shifts are not included.
