Convert coordinates from DHDN (EPSG:4314) to ETRS89 (EPSG:4258) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
The EPSG Geodetic Parameter Dataset defines 9 transformations between DHDN (EPSG:4314) and ETRS89 (EPSG:4258). Each applies to a specific area — pick the one whose area of use covers your data.
Grid file: SeTa2016.gsb
Replaces SeTa2009 from 2018-01-15. Derived using the 2016 implementation of ETRS89 / DREF91 and DHHN2016. Coincident with the transformation of cadastral data from DHDN to ETRS89 used by LVGL at a level of 1-2 mm.
Grid file: BWTA2017.gsb
Official transformation for the state of Baden-Württemberg. Used in ATKIS (Amtliches Topographisch-Kartographisches Informationssystem [Official Topographic and Cartographic Information System]).
Grid file: HeTa2010.gsb
Official transformation of Hessen for the land survey register (ALKIS).
Grid file: BETA2007.gsb
Developed for ATKIS (Amtliches Topographisch-Kartographisches Informationssystem [Official Topographic and Cartographic Information System]). Provides a uniform transformation across the whole country. May be used as tfm to WGS 84 - see tfm code 15949.

Mean of 69 stations. May be taken as approximate tfm DHDN to WGS 84 (code 1673). Replaced by DHDN to ETRS89 (2) (tfm code 1776) and regional higher accuracy tfms. Note: these later tfms have been published using the Position Vector method.
The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4314", "EPSG:4258", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
