Lat Long To UTM Converter

Lat Long to UTM Converter

Convert geographic coordinates to UTM

Saved Calculations
No history yet. Calculate below to start tracking.

The Universal Transverse Mercator (UTM) system divides the Earth into 60 zones and projects coordinates as flat Easting/Northing meters within each zone — useful for distance and area calculations that decimal lat/long can't do directly.

Enter a latitude and longitude in decimal degrees (WGS84) to get the UTM zone, hemisphere, easting and northing.

Latitude

Valid UTM range: -80° to 84° (polar regions use UPS instead).

Full UTM Details
Uses the WGS84 ellipsoid, the standard reference for GPS coordinates.

Decimal latitude and longitude are convenient for GPS, but the UTM projection makes distance and area calculations far simpler by expressing location as flat meters instead of angular degrees. This converter translates your coordinates into the correct UTM zone, hemisphere, easting, and northing.

How to use this lat long to UTM converter

  1. Enter your Latitude in decimal degrees (valid range: -80° to 84°).
  2. Enter your Longitude in decimal degrees.
  3. Read your UTM Zone, Hemisphere, and full UTM Coordinate (Easting/Northing).

What this converter does

The Universal Transverse Mercator (UTM) system divides the Earth into 60 numbered zones and projects coordinates within each zone as flat Easting/Northing values in meters. This flat projection makes distance and area calculations straightforward within a zone in a way that raw decimal latitude/longitude, being angular measurements on a sphere, cannot support directly.

Why UTM has a valid latitude range limit

UTM is only valid between 80°S and 84°N. Beyond those limits, near the poles, the Universal Polar Stereographic (UPS) system is used instead, since the UTM projection becomes too distorted to be useful that close to the poles.

Why this converter uses WGS84

This converter uses the WGS84 ellipsoid, the standard reference datum for GPS coordinates worldwide, ensuring compatibility with the coordinates your GPS device or mapping app actually reports.

Frequently asked questions

Why does UTM have a latitude range limit?

UTM is valid between 80°S and 84°N; beyond that range, near the poles, the projection becomes too distorted, and the Universal Polar Stereographic (UPS) system is used instead.

Why convert to UTM instead of just using decimal degrees?

UTM projects coordinates as flat, planar Easting/Northing meters within each zone, which makes distance and area calculations straightforward in a way that angular decimal degrees on a sphere cannot support directly.
