Nordic Geodetic Commission (NKG) 2020 transformation. Replaces NKG2008 transformation. Because the difference in coordinates between NKG_ETRF14 and EUREF-FIN is small (under a decimetre), although the interpolation CRS is given as NKG_ETRF14, any realization of ETRS89 (including ETRF2014 and EUREF-FIN) may be used as the interpolation CRS. Scale difference in ppb where 1/billion = 1E-9.

Frequently asked questions

How accurate is converting NKG_ETRF14 to EUREF-FIN?
The most accurate official EPSG transformation between these systems is accurate to about ±0.002 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation in a desktop GIS.
Does my data leave the browser when I use this converter?
No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
