Both source and target CRS must be supplied. Axis order follows Proj4js x/y conventions, not latitude-first display order.

Understanding EPSG Coordinate Converter

Coordinate systems, order and units

Transform one coordinate between explicit EPSG coordinate reference systems with Proj4js in your browser.

EPSG Coordinate Converter depends on knowing how coordinates are expressed. Geographic coordinates commonly use WGS84 longitude and latitude, while projected systems use linear units and a defined datum and projection.

How to verify the coordinates

Both source and target CRS must be supplied. Axis order follows Proj4js x/y conventions, not latitude-first display order.

To verify EPSG Coordinate Converter, spot-check a known place, confirm axis order and verify the expected unit and CRS. A numerically valid coordinate can still be geographically wrong when those assumptions are incorrect.
