Worked example — the centre of this system's area of use: 15, 42 (EPSG:4326 lon, lat) = 500,000, 4,649,776.22 (EPSG:32633).

EPSG:32633 is WGS 84 / UTM zone 33N — the UTM band covering 12°E to 18°E in the northern hemisphere: most of Italy, eastern Germany, Austria, Poland, Czechia, Croatia, Norway and a broad strip of central Africa. Coordinates are eastings and northings in metres.

Like every UTM zone it is excellent for measurement and analysis within its 6° band: scale error stays below 1 part in 1,000. If your data spans multiple zones, pick the zone of the data centre or use a continental system instead.

Frequently asked questions

How do I know if my data is in UTM zone 33N?

Eastings will be between roughly 166,000 and 834,000 m and northings between 0 and 9,330,000 m, with the data located between 12°E and 18°E. Rome, for example, is about E 291,000, N 4,640,000 in zone 33N.

What is the difference between EPSG:32633 and EPSG:25833?

Same projection (UTM 33N), different datum: 32633 is on WGS 84, 25833 on ETRS89. In Europe they currently differ by less than a metre. European agencies mandate 25833; 32633 is the natural choice for GPS-derived or global datasets.

What happens if I use zone 33N for data outside 12°E–18°E?

The math still works — coordinates just grow beyond the normal easting range and distortion increases with distance from the zone. A few degrees of overshoot is often acceptable; reprojecting a whole country several zones away is not.
