Frequently asked questions

How do I convert UTM to latitude/longitude?

Pick the correct UTM zone as the input CRS (for example EPSG:32632 for WGS 84 / UTM zone 32N), enter the easting as X and northing as Y, and set the output to EPSG:4326 (WGS 84). The tool reprojects with proj4 and returns decimal-degree longitude and latitude. Choosing the wrong zone is the usual cause of a result that's hundreds of kilometres off.

What is EPSG:4326?

EPSG:4326 is WGS 84, the geographic coordinate reference system used by GPS and the default for GeoJSON. Coordinates are decimal degrees of longitude and latitude on the WGS 84 datum, worldwide. Note that EPSG:4326 defines axis order as latitude, longitude — while GeoJSON stores the same datum as longitude, latitude.

Decimal degrees vs DMS — what's the difference?

They're two notations for the same angle. Decimal degrees write it as a single number (52.520008°); degrees-minutes-seconds split it into whole degrees, arc-minutes and arc-seconds (52° 31' 12.03" N). One degree is 60 minutes and one minute is 60 seconds, so 0.5° equals 30'. Most software and GeoJSON use decimal degrees.
