Official EPSG transformations from MGI to WGS 84

The EPSG Geodetic Parameter Dataset defines 2 transformations between MGI (EPSG:4312) and WGS 84 (EPSG:4326). Each applies to a specific area — pick the one whose area of use covers your data.

MGI to WGS 84 (8)

EPSG:1194±0.5 mBest accuracy
Method:
Coordinate Frame rotation (geog2D domain)
Area of use:
Austria - Styria
Scope:
Transformation of coordinates at 0.5m level of accuracy.
ParameterValueUnit
X-axis translation(tx)601.705metre
Y-axis translation(ty)84.263metre
Z-axis translation(tz)485.227metre
X-axis rotation(rx)-4.7354arc-second
Y-axis rotation(ry)-1.3145arc-second
Z-axis rotation(rz)-5.393arc-second
Scale difference(ds)-2.3887parts per million

May be taken as approximate transformation MGI to ETRS89 assuming ETRS89 is equivalent to WGS 84 within the accuracy of the transformation - see tfm code 1024. Information source gives scale as -2.388739 ppm.

MGI to WGS 84 (3)

EPSG:1618±1.5 m
Method:
Position Vector transformation (geog2D domain)
Area of use:
Austria
Scope:
(null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
ParameterValueUnit
X-axis translation(tx)577.326metre
Y-axis translation(ty)90.129metre
Z-axis translation(tz)463.919metre
X-axis rotation(rx)5.137arc-second
Y-axis rotation(ry)1.474arc-second
Z-axis rotation(rz)5.297arc-second
Scale difference(ds)2.4232parts per million

Same transformation parameters used for MGI to ETRS89 (1) (code 1619).

Frequently asked questions

How accurate is converting MGI to WGS 84?
The most accurate official EPSG transformation between these systems is accurate to about ±0.5 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.
