Transform Coordinates

Remarks

Parameter values from RT90 to ETRS89 (1) (code 1437) assuming that ETRS89 is equivalent to WGS 84 within the accuracy of the transformation. Replaced by RT90 to WGS 84 (2) (code 1896) from 2001.

Frequently Asked Questions

How do I convert RT90 to WGS 84 coordinates?

Use the coordinate transformation tool above to convert RT90 (EPSG:4124) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Coordinate Frame rotation (geog2D domain) method with 1m accuracy.

How do I transform RT90 to WGS 84 using Proj4js?

Use proj4.defs to define both EPSG:4124 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the RT90 to WGS 84 transformation?

This transformation (EPSG:1680) has an accuracy of 1m using the Coordinate Frame rotation (geog2D domain) method. Area of use: Sweden.
