Frequently asked questions
- How accurate is converting Aratu / UTM zone 23S to WGS 72?
- 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.
