Official EPSG transformations from DHDN to WGS 84

The EPSG Geodetic Parameter Dataset defines 4 transformations between DHDN (EPSG:4314) and WGS 84 (EPSG:4326). Each applies to a specific area — pick the one whose area of use covers your data.

DHDN to WGS 84 (4)

EPSG:15949±1 mBest accuracy

Method:: NTv2
Area of use:: Germany - onshore
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.

Grid file: BETA2007.gsb

These parameter values are taken from DHDN to ETRS89 (8) (code 15948) as ETRS89 may be considered equivalent to WGS 84 within the accuracy of the transformation.

DHDN to WGS 84 (3)

EPSG:15869±2 m

Method:: Position Vector transformation (geog2D domain)
Area of use:: Germany - East Germany all states
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.

Parameter	Value	Unit
X-axis translation(tx)	612.4	metre
Y-axis translation(ty)	77	metre
Z-axis translation(tz)	440.2	metre
X-axis rotation(rx)	-0.054	arc-second
Y-axis rotation(ry)	0.057	arc-second
Z-axis rotation(rz)	-2.797	arc-second
Scale difference(ds)	2.55	parts per million

Parameter values taken from RD/83 to ETRS89 (1) (tfm code 15868) assuming that within the accuracy of the transformation ETRS89 is equivalent to WGS 84 and RD/83 is equivalent to DHDN.

DHDN to WGS 84 (2)

EPSG:1777±3 m

Method:: Position Vector transformation (geog2D domain)
Area of use:: Germany - West Germany all states
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.

Parameter	Value	Unit
X-axis translation(tx)	598.1	metre
Y-axis translation(ty)	73.7	metre
Z-axis translation(tz)	418.2	metre
X-axis rotation(rx)	0.202	arc-second
Y-axis rotation(ry)	0.045	arc-second
Z-axis rotation(rz)	-2.455	arc-second
Scale difference(ds)	6.7	parts per million

Parameter values from DHDN to ETRS89 (2) (code 1776) assuming that ETRS89 is equivalent to WGS 84 within the accuracy of the transformation. Replaces DHDN to WGS 84 (1) (tfm code 1673).

DHDN to WGS 84 (1)

EPSG:1673±5 m

Method:: Coordinate Frame rotation (geog2D domain)
Area of use:: Germany - West Germany all states
Scope:: Transformation of coordinates at 5m level of accuracy.

Parameter	Value	Unit
X-axis translation(tx)	582	metre
Y-axis translation(ty)	105	metre
Z-axis translation(tz)	414	metre
X-axis rotation(rx)	-1.04	arc-second
Y-axis rotation(ry)	-0.35	arc-second
Z-axis rotation(rz)	3.08	arc-second
Scale difference(ds)	8.3	parts per million

Parameter values from DHDN to ETRS89 (1) (code 1309) assuming that ETRS89 is equivalent to WGS 84 within the accuracy of the transformation. Replaced by DHDN to WGS 84 (2) (tfm code 1777).

Frequently asked questions

How accurate is converting DHDN to WGS 84?: The most accurate official EPSG transformation between these systems is accurate to about ±1 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation (including the grid-shift files listed below) 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.
