About converting WGS 84 to SVY21 / Singapore TM
Converting from WGS 84 (EPSG:4326) to SVY21 (EPSG:3414) is the standard transformation for working with Singapore Land Authority cadastral and government mapping data. SVY21 is a Transverse Mercator projection on the WGS 84 ellipsoid centred at 1°22'N 103°50'E with a tiny offset that keeps Singapore coordinates as positive metric values within a manageable range.
Because SVY21 uses the WGS 84 ellipsoid with only a small projection offset, the conversion is essentially a deterministic projection step — no datum shift is required for sub-metre accuracy.

Frequently asked questions
- Is SVY21 a true datum or just a projection?
- SVY21 uses the WGS 84 ellipsoid; the difference from EPSG:4326 is purely a projection (Transverse Mercator + small offset to keep coordinates positive over Singapore).
- How accurate is converting WGS 84 to SVY21 / Singapore TM?
- 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.
