Convert coordinates from Schwarzeck (EPSG:4293) 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 2 transformations between Schwarzeck (EPSG:4293) 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) | 616 | metre |
| Y-axis translation(ty) | 97 | metre |
| Z-axis translation(tz) | -251 | metre |
Derived at 3 stations. Accuracy 20m in each axis. Beware! Source CRS uses German legal metres, transformation parameter values are in (International) metres. See tfm code 1271 for example.
| Parameter | Value | Unit |
|---|---|---|
| X-axis translation(tx) | 615.64 | metre |
| Y-axis translation(ty) | 102.08 | metre |
| Z-axis translation(tz) | -255.81 | metre |
Beware! Source CRS uses GLM, tfm param in m. Example: Schwarzeck φ=19°35'46.952"S λ=20°41'50.649"E h=1185.99m; X=5623409.386 Y=2124618.003 Z=-2125847.632 GLM; X=5623485.84m Y=2124646.89m Z=-2125876.54m; WGS 84 X=5624101.48m Y=2124748.97m Z=-2126132.35m.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4293", "EPSG:4326", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
