The EPSG dataset defines official transformation parameters for the reverse direction. See IGS00 to IGb00 — the parameters are invertible.

Convert EPSG:9007 to EPSG:9004 in code

The same transformation with common GIS tools and libraries:

from pyproj import Transformer

transformer = Transformer.from_crs("EPSG:9007", "EPSG:9004", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
print(x, y)

Frequently asked questions

How accurate is converting IGb00 to IGS00?
Projection-only conversions are accurate to floating-point precision. If a datum shift is involved, browser-based tools use Helmert parameters which are accurate to roughly 1-5 m; for surveying-grade work apply the official grid-shift 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.
