Remarks
Approximation at the +/- 1m level assuming that Hong Kong Geodetic CS is equivalent to WGS 84.
Frequently Asked Questions
How do I convert Hong Kong Geodetic CS to WGS 84 coordinates?
Use the coordinate transformation tool above to convert Hong Kong Geodetic CS (EPSG:8427) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 1m accuracy.
How do I transform Hong Kong Geodetic CS to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:8427 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Hong Kong Geodetic CS to WGS 84 transformation?
This transformation (EPSG:8439) has an accuracy of 1m using the Geocentric translations (geog2D domain) method. Area of use: Hong Kong.
