UTM Zone Finder — Find Your UTM Zone on a Map
Click a point on the map or enter coordinates; instantly find the UTM zone, EPSG code, band and hemisphere.
UTM Zone System
The world is divided into 6-degree longitude bands (zones 1–60). Each zone has a separate EPSG code for the northern/southern hemisphere. Turkey generally falls in zones 35–37.

Understanding UTM Zones
The Universal Transverse Mercator (UTM) system divides the Earth between 80° S and 84° N into 60 vertical columns (zones), each 6° of longitude wide and numbered 1 to 60 eastward from the 180° meridian. Every zone has its own central meridian and applies a Transverse Mercator projection that keeps scale distortion below 0.1% within the zone boundaries — making it one of the most accurate flat-plane coordinate systems for regional work.
Each UTM zone is further divided into North and South hemispheres. Coordinates within a zone are expressed as Easting (meters east of the central meridian, offset by 500,000 m to avoid negative values) and Northing (meters from the equator, offset by 10,000,000 m in the southern hemisphere). This makes UTM ideal for any application requiring metric measurements at a regional scale.
Who Uses UTM and Why
- Land surveyors and engineers use UTM because coordinates are in meters, enabling direct distance and area calculations without complex ellipsoidal formulas.
- Military and emergency services rely on UTM grid references as a standard for locating positions in the field, often via GPS devices that display UTM coordinates.
- GIS analysts set data layers to a UTM CRS before running spatial analysis operations — buffer, intersect, area calculation — that require metric units.
- Remote sensing specialists process satellite imagery in UTM to align pixels with real-world meter-based grids for classification and change detection.
How to Use This Tool
Enter a latitude and longitude in the input fields and click Find UTM Zone, or simply click any point on the interactive map. The tool instantly returns the UTM zone number, hemisphere (North or South), the central meridian, and the EPSG code for that zone. Results can be used directly in GIS software or as the SRID in a spatial database query.
Reading Your UTM Result
A result of "Zone 36N" means the location is in UTM zone 36, northern hemisphere, with EPSG code 32636. The "N" indicates north of the equator — use EPSG:327XX for southern hemisphere zones. If a location is close to a zone boundary (every 6° longitude), double-check which zone your data was originally captured in to avoid a 500 km easting offset.
Other Tools
After finding your UTM zone, use the Coordinate Converter to transform coordinates from geographic (lat/lon) to UTM Easting/Northing. For full coordinate system details, look up the EPSG code in our EPSG Code Finder. The DMS ↔ Decimal Degrees tool helps convert GPS coordinates to the decimal format needed here.
Frequently Asked Questions
What is a UTM zone?
UTM (Universal Transverse Mercator) divides the world into 60 vertical zones, each 6 degrees of longitude wide, numbered 1 to 60 from west to east starting at 180° longitude. Each zone has its own central meridian and uses a Transverse Mercator projection that minimizes distortion within that band. The combination of zone number and hemisphere (North or South) fully defines the coordinate system for any location.
What UTM zone am I in?
Your UTM zone depends on your longitude. Divide your longitude by 6, round up, and add 1 to get the zone number. For example, longitude 32° East falls in UTM Zone 36. This tool calculates it automatically — just enter your coordinates or click the map to get the zone number, hemisphere, and corresponding EPSG code instantly.
What is the EPSG code for a UTM zone?
UTM zones on the WGS 84 datum have standardized EPSG codes. Northern hemisphere zones use EPSG:326XX where XX is the zone number (e.g., EPSG:32636 for UTM Zone 36N). Southern hemisphere zones use EPSG:327XX (e.g., EPSG:32736 for UTM Zone 36S). This tool displays the correct EPSG code alongside the zone result.
Why is UTM used instead of geographic coordinates for measurements?
Geographic coordinates (latitude/longitude) are angles on an ellipsoid, making direct distance and area calculations complex and inaccurate at large scales. UTM is a projected system that represents positions in meters on a flat plane, so you can calculate distances and areas with simple formulas. GIS workflows requiring accurate measurements — such as land surveys, infrastructure planning, and environmental analysis — typically work in UTM or another local projected CRS.
Does UTM cover the entire Earth?
UTM covers latitudes from 80° South to 84° North. The polar regions are covered by the Universal Polar Stereographic (UPS) projection instead. Norway and Svalbard use special UTM zone modifications in zones 32 and 34. For locations near zone boundaries, it is important to use the correct zone to avoid large coordinate errors.
How do I convert latitude and longitude to UTM coordinates?
Use this tool to first find your UTM zone and its EPSG code. Then use our Coordinate Converter to transform decimal degree latitude/longitude values into UTM Easting and Northing in meters. The resulting coordinates can be used directly in GIS software, spatial databases, or field survey equipment.
What is the UTM zone for Turkey?
Turkey spans UTM zones 35, 36, 37, and 38, all in the northern hemisphere. Most of the country falls in zones 36N (EPSG:32636) and 37N (EPSG:32637). Turkish national mapping uses the TUREF datum with Transverse Mercator projections, but UTM on WGS 84 is commonly used in international GIS workflows and GPS-based surveys.
