Official EPSG transformation from WGS 84 (G2139) to WGS 84 (G2296)

The EPSG Geodetic Parameter Dataset defines 1 transformation between WGS 84 (G2139) (EPSG:9753) and WGS 84 (G2296) (EPSG:10604). Its parameters, accuracy and area of use are listed below.

WGS 84 (G2139) to WGS 84 (G2296) (1)

EPSG:10607±0.01 m

Method:: Coordinate Frame rotation (geocentric domain)
Area of use:: World
Scope:: Geodesy.

Parameter	Value	Unit
X-axis translation(tx)	2.6	millimetre
Y-axis translation(ty)	5.4	millimetre
Z-axis translation(tz)	-0.9	millimetre
X-axis rotation(rx)	-0.01	milliarc-second
Y-axis rotation(ry)	-0.07	milliarc-second
Z-axis rotation(rz)	0	milliarc-second
Scale difference(ds)	0.06	parts per billion

Scale difference in ppb where 1/billion = 1E-9 or nm/m. Calculated by extrapolating the position and velocity of the seventeen WGS 84 GPS monitoring sites to the epoch 2024.00.

Frequently asked questions

How accurate is converting WGS 84 (G2139) to WGS 84 (G2296)?: The most accurate official EPSG transformation between these systems is accurate to about ±0.01 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.
