Coordinate converter
Convert between SWEREF 99 TM, WGS84, RT90 and local SWEREF projections. Single points or batch – fully in the browser.
Conversion runs locally in your browser using open proj4 definitions of the Swedish coordinate systems. Always verify results against the official source (Lantmäteriet) before use in production projects.
This tool is an aid – not a replacement for professional surveying or inspection. Intely is not liable for decisions made solely on the basis of the result. Contact us for a verified delivery.
