About UTM Zone 40N
UTM zone 40N covers longitudes 54°E to 60°E in the northern hemisphere, with its central meridian at 57°E. On the WGS 84 datum it needs no datum shift, so eastings and northings convert straight to the latitude and longitude Google Earth uses.
Where it's used: Abu Dhabi city, Dubai, Sharjah and the northern emirates, Oman including Muscat, and eastern Iran.
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 “32640” and pick WGS 84 / UTM zone 40N.
- Check one point you know on the map, then press Save KML or Save KMZ (with photos) and open it in Google Earth.
Check points for UTM Zone 40N
Five points inside the area of use of UTM Zone 40N, 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 | 42.00000° N | 57.00000° E | 500,000.00 | 4,649,776.22 |
| Towards the north-west | 67.20000° N | 55.20000° E | 422,169.82 | 7,454,802.98 |
| Towards the north-east | 67.20000° N | 58.80000° E | 577,830.18 | 7,454,802.98 |
| Towards the south-west | 16.80000° N | 55.20000° E | 308,173.65 | 1,858,301.37 |
| Towards the south-east | 16.80000° N | 58.80000° E | 691,826.35 | 1,858,301.37 |
Common mistakes with UTM Zone 40N
- Easting and northing swapped. In UTM Zone 40N the middle of the grid is near easting 500,000.00 and northing 4,649,776.22. If your easting column holds numbers like 4,649,776.22, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. UTM Zone 40N is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
- Looking for a datum shift that isn't there. UTM Zone 40N is defined on WGS 84, the datum Google Earth uses, so no shift is applied. If points are off by tens or hundreds of metres, the data is probably on another grid.
- Points outside the grid's area. UTM Zone 40N is meant for Between 54°E and 60°E, northern hemisphere between equator and 84°N, onshore and offshore. Islamic Republic of Iran. kazakhstan. Oman. Russian Federation. Saudi Arabia. Turkmenistan. United Arab Emirates. Uzbekistan. 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.
Before you rely on it
Pick the zone by longitude, not by country: a project near 60°E may belong in the next zone. Points outside the zone are flagged after conversion. Always check one known control point before sending a file out.
