Good to know
- This is a southern-hemisphere grid: northings start at 10,000,000 m at the equator.
- Pick the UTM zone by longitude. Points outside the zone's area of use are flagged after conversion.
- Datum: Treated as WGS 84, no shift (the datums agree to about a metre or better).
Convert a whole spreadsheet
- Open the web app or the Windows app, and paste your rows from Excel or open a CSV file.
- Under Coordinate system, search for “8903” and pick RGWF96 / UTM zone 1S.
- Check one point you know on the map, then press Save KML or Save KMZ and open it in Google Earth.

Five points inside the area of use of RGWF96 / UTM zone 1S, with their latitude and longitude on WGS 84 and their easting and northing in this grid (metres). Enter an easting and northing in the converter above: you should get the latitude and longitude shown, to a few centimetres.
| Point | Latitude | Longitude | Easting | Northing |

| Middle of the area of use | 12.89000° S | 177.39000° W | 457,689.02 | 8,574,996.59 |
| Towards the north-west | 11.06000° S | 179.26200° W | 252,880.66 | 8,776,450.17 |
| Towards the north-east | 11.06000° S | 175.51800° W | 661,883.38 | 8,776,984.63 |

Common mistakes with RGWF96 / UTM zone 1S
- Easting and northing swapped. In RGWF96 / UTM zone 1S the middle of the grid is near easting 457,689.02 and northing 8,574,996.59. If your easting column holds numbers like 8,574,996.59, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. RGWF96 / UTM zone 1S is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
- Forgetting the datum. RGWF96 / UTM zone 1S is not on WGS 84: treated as WGS 84, no shift (the datums agree to about a metre or better). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. RGWF96 / UTM zone 1S is meant for Wallis and Futuna - onshore and offshore - Uvea, Futuna, and Alofi. Points well outside that area convert with growing error; the converter flags them so you can choose the right grid.
- A local site grid. If every point is off by the same distance and direction, the drawing may be on a local site grid. Calibrate on three or more known control points instead.
