What does the Latitude Longitude to UTM Calculator do?

The Latitude Longitude to UTM Calculator converts a WGS84 latitude/longitude coordinate pair into a UTM coordinate, including the UTM zone number, hemisphere (N/S), easting, and northing values.

How is the UTM zone calculated?

UTM Zone = floor((longitude + 180) / 6) + 1. The Latitude Longitude to UTM Calculator applies this formula automatically and also determines whether the point is in the northern or southern hemisphere.

Why does the Latitude Longitude to UTM Calculator only support -80° to 84° latitude?

The UTM system is defined only between 80° S and 84° N. Polar regions use separate coordinate systems (UPS). The Latitude Longitude to UTM Calculator will warn you if your latitude falls outside this range.

What datum does the Latitude Longitude to UTM Calculator use?

The calculator uses the WGS84 datum, which is the standard for GPS and most modern mapping applications.

No. All calculations happen in your browser; nothing is sent to a server.

How to Use Latitude Longitude to UTM Calculator

The Latitude Longitude to UTM Calculator converts geographic coordinates (latitude/longitude) into the UTM projected coordinate system used in mapping, GIS, and surveying.

Enter Latitude — Type the decimal latitude value between -80 and 84 degrees. Positive values are North, negative values are South.
Enter Longitude — Type the decimal longitude value between -180 and 180 degrees. Positive values are East, negative values are West.
Read the result — The Latitude Longitude to UTM Calculator displays UTM Zone, Hemisphere, Easting, Northing, and the full formatted UTM coordinate string.

Input validation is built in: if latitude or longitude falls outside the valid UTM range, the Latitude Longitude to UTM Calculator shows a clear error message.

Formula & Theory — Latitude Longitude to UTM Calculator

The Latitude Longitude to UTM Calculator uses the WGS84 ellipsoid parameters and the standard Transverse Mercator projection:

UTM Zone   = floor((longitude + 180) / 6) + 1
Central meridian (λ₀) = (Zone − 1) × 6 − 180 + 3

Scale factor k₀ = 0.9996
False Easting   = 500 000 m
False Northing  = 10 000 000 m (Southern hemisphere only)

Parameter	Value
Semi-major axis (a)	6 378 137.0 m
Flattening (1/f)	298.257 223 563
Scale factor (k₀)	0.9996

The Latitude Longitude to UTM Calculator applies the full series expansion for the Transverse Mercator projection to compute Easting and Northing from latitude and longitude. Results are accurate to within approximately 1 mm for most practical locations within a UTM zone.

UTM Zone Boundaries

Each UTM zone spans 6° of longitude. There are 60 zones numbered 1 to 60. The Latitude Longitude to UTM Calculator automatically identifies the correct zone based on your input longitude.

Use Cases for Latitude Longitude to UTM Calculator

The Latitude Longitude to UTM Calculator is widely used across multiple disciplines:

GIS and spatial analysis — Convert GPS decimal coordinates into UTM for use in GIS software such as QGIS or ArcGIS, where metric-based UTM coordinates simplify distance and area calculations.
Outdoor navigation — Hikers and mountaineers use the Latitude Longitude to UTM Calculator to convert phone GPS readings to UTM for topographic maps.
Surveying and land mapping — Surveyors convert reference points from GPS receivers to UTM before computing traverses or importing into CAD tools.
Military and emergency services — UTM is the coordinate system used in military grid references (MGRS); the Latitude Longitude to UTM Calculator provides the foundation coordinates.
Geographic data processing — Data engineers preparing spatial datasets convert latitude/longitude fields to UTM easting/northing for metric-based analysis pipelines.

If you need to go the other direction, you can use a UTM to Latitude Longitude Calculator to reverse the conversion back to geographic coordinates.
