Convert coordinates from Arc 1960 (EPSG:4210) to WGS 84 (EPSG:4326) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
The EPSG Geodetic Parameter Dataset defines 4 transformations between Arc 1960 (EPSG:4210) and WGS 84 (EPSG:4326). Each applies to a specific area — pick the one whose area of use covers your data.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -157 | metre |
| Y-axis translation(ty) | -2 | metre |
| Z-axis translation(tz) | -299 | metre |
Derived at 24 stations. Accuracy 4m, 3m and 3m in X, Y and Z axes.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -175 | metre |
| Y-axis translation(ty) | -23 | metre |
| Z-axis translation(tz) | -303 | metre |
Derived at 12 stations. Accuracy 6m, 9m and 10m in X, Y and Z axes.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -160 | metre |
| Y-axis translation(ty) | -6 | metre |
| Z-axis translation(tz) | -302 | metre |
Derived at 25 stations. Accuracy 20m in each axis.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | -153 | metre |
| Y-axis translation(ty) | -5 | metre |
| Z-axis translation(tz) | -292 | metre |
Derived at 3 stations. Accuracy 20m in each axis. Info source gives source CRS as Arc 1950. From inspection of parameter values, analysis of TR8350.2 contour chart and geographic applicability of CRS, OGP believes that the this should be Arc 1960.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4210", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
