Frequently Asked Questions
What is the difference between WGS84 and UTM Zone 30N?
WGS84 (EPSG:4326) is geographic and based in Global, while UTM Zone 30N (EPSG:32630) is utm based in Global. The global reference system used by GPS, Google Maps and virtually all modern navigation. Defined by satellite geodesy and continuously refined. In contrast, utm zone 30n covers 6° to 0° west — uk, portugal, western spain, western france.
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 WGS84, enter coordinates as decimal degrees in the format "lat, lng" (e.g. 45.4642, 9.1900). 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:4326&to=EPSG:32630&coords=lat,lng for programmatic access. It returns the transformed coordinates as JSON.
