Remarks
Considered exact at 1994-01-01 when SVY21 aligned to WGS 84 (Transit).
Frequently Asked Questions
How do I convert SVY21 to WGS 84 coordinates?
Use the coordinate transformation tool above to convert SVY21 (EPSG:4757) 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 SVY21 to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:4757 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the SVY21 to WGS 84 transformation?
This transformation (EPSG:8886) has an accuracy of 1m using the Geocentric translations (geog2D domain) method. Area of use: Singapore.
