Use zone 31 north with easting 448251 and northing 5411932, which lands right beside the Eiffel Tower in Paris.
The calculations use the WGS 84 ellipsoid, the same datum used by GPS receivers and most online maps.
Southern hemisphere northings add ten million metres so that every value stays positive within its zone.
Each UTM zone is split into bands of eight degrees of latitude, labelled from C near the south to X near the north.
Switch to latitude and longitude to UTM. The zone is worked out automatically from the longitude of your point.
The series expansion used here is accurate to about one millimetre inside a zone and drifts only slightly outside it.
No. The conversion is done in your browser, so the coordinates you type never leave your device.
