About Web Mercator
Pseudo-Mercator / Spherical Mercator (EPSG:3857). The projection used by Google Maps, OpenStreetMap and most web mapping. Not suitable for precise surveying due to scale distortion.
About UTM Zone 32N
WGS84 / UTM zone 32N (central Europe, Italy) (EPSG:32632). UTM zone 32N covers 6° to 12° East longitude — Italy, Switzerland, western Germany, Austria, Tunisia. One of the most-used surveying zones in Europe.
Frequently Asked Questions
What is the difference between Web Mercator and UTM Zone 32N?
Web Mercator (EPSG:3857) is projected and based in Global, while UTM Zone 32N (EPSG:32632) is utm based in Global. The projection used by Google Maps, OpenStreetMap and most web mapping. Not suitable for precise surveying due to scale distortion. In contrast, utm zone 32n covers 6° to 12° east longitude — italy, switzerland, western germany, austria, tunisia. one of the most-used surveying zones in europe.
Is this conversion accurate for surveying?
Yes. The conversion uses the industry-standard proj4 library with full datum shift parameters (). Typical accuracy is sub-meter for civilian applications. For cadastral precision, always verify against the official agency datum.
What coordinate format should I use?
For Web Mercator, enter coordinates as easting, northing in meters (e.g. 514500, 5033880). The tool auto-detects the format.
Can I convert many points at once?
Yes, use our batch CSV converter. Upload a CSV with your points, select the transformation, download the converted file. Free with a SurveyingPedia account.
Is there an API?
Yes — call /api/v1/transform?from=EPSG:3857&to=EPSG:32632&coords=lat,lng for programmatic access. It returns the transformed coordinates as JSON.
