Convert EPSG:4322 to EPSG:4275
Online coordinate converter from WGS 72 (EPSG:4322) to NTF (EPSG:4275). Enter your source coordinates and get the result instantly. All transformations happen in your browser — no data is sent to any server.
The EPSG dataset defines official transformation parameters for the reverse direction. See NTF to WGS 72 — the parameters are invertible.

The same transformation with common GIS tools and libraries:
from pyproj import Transformer
transformer = Transformer.from_crs("EPSG:4322", "EPSG:4275", always_xy=True)
x, y = transformer.transform(-73.9857, 40.7484)
print(x, y)Target: EPSG:4275 — NTF

Frequently asked questions
- How accurate is converting WGS 72 to NTF?
- 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.
