About converting WGS 84 to ETRS89
Converting from WGS 84 (EPSG:4326) to ETRS89 (EPSG:4258) is the standard transformation for harmonising GPS-derived data with INSPIRE-compliant European spatial datasets. ETRS89 is fixed to the Eurasian plate at epoch 1989; WGS 84 tracks ITRF globally. The two currently differ across Europe by roughly 60 cm and accumulating ~2.5 cm/year.
For most visualisation and exchange the difference is invisible. For surveying-grade work apply the published Helmert transformation against a specific ETRS89 realisation (e.g. ETRF2000 or the national realisation: ETRS89-DREF91 in Germany, ETRS89/RGF93 in France).
Why people convert EPSG:4326 to EPSG:4258
- INSPIRE-compliant European data exchange
- Imports into national mapping (DE, FR, ES, NL)
- Surveying with European CORS networks (EUREF)
- Aligning satellite imagery with ETRS89 cadastral data
The EPSG dataset defines official transformation parameters for the reverse direction. See ETRS89 to WGS 84 — the parameters are invertible.

transformer = Transformer.from_crs("EPSG:4326", "EPSG:4258", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)

Frequently asked questions
- Why is the WGS 84 to ETRS89 difference growing?
- ETRS89 is frozen to the Eurasian plate at epoch 1989; WGS 84 tracks the global ITRF, which drifts with the plate. The gap accumulates at roughly the rate of plate motion — about 2.5 cm/year in central Europe.
- How accurate is converting WGS 84 to ETRS89?
- Projection-only conversions are accurate to floating-point precision. If a datum shift is involved, browser-based tools use Helmert parameters which are accurate to roughly 1-5 m; for surveying-grade work apply the official grid-shift 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.
