Good to know
- 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 “3187” and pick GR96 / UTM zone 27N.
- 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 GR96 / UTM zone 27N, 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 | 75.85000° N | 21.00000° W | 500,000.00 | 8,418,447.98 |
| Towards the north-west | 80.74000° N | 22.80000° W | 467,669.01 | 8,964,684.20 |
| Towards the north-east | 80.74000° N | 19.20000° W | 532,330.99 | 8,964,684.20 |

Common mistakes with GR96 / UTM zone 27N
- Easting and northing swapped. In GR96 / UTM zone 27N the middle of the grid is near easting 500,000.00 and northing 8,418,447.98. If your easting column holds numbers like 8,418,447.98, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. GR96 / UTM zone 27N 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. GR96 / UTM zone 27N 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. GR96 / UTM zone 27N is meant for Greenland - between 24°W and 18°W, onshore and offshore south of 84°N. 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.
