🗺️ Lat/Long to UTM Converter
Translate geographic coordinates into Universal Transverse Mercator (UTM) coordinates.
Enter latitude and longitude in decimal degrees. The converter outputs UTM zone, easting, northing, and hemisphere based on the WGS84 datum.
Valid range: -90 to +90. North is positive.
Valid range: -180 to +180. East is positive.
UTM Coordinates (WGS84)
Zone: 18N
Easting: 583959.37 m
Northing: 4507351.00 m
Input Coordinates
Latitude (DMS): 40° 42' 46.08" N
Longitude (DMS): 74° 0' 21.60" W
DMS provided for reference; conversions use decimal degrees.
How to Use This Calculator
Enter decimal latitude and longitude
Use WGS84 coordinates (the default for GPS). Negative values represent south or west.
Verify the UTM zone
The converter assigns the correct UTM zone and hemisphere automatically.
Copy easting and northing
Use the meter-based UTM coordinates in CAD, surveying software, or GIS systems.
Formula
The converter implements the WGS84 Transverse Mercator projection with scale factor k₀ = 0.9996, applying standard series expansions for northing/easting within ±84° latitude.
Easting includes a 500,000 m false easting. South hemisphere northing adds 10,000,000 m false northing.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
UTM coordinates simplify distance calculations by projecting the globe into 6° longitudinal zones. Surveyors, engineers, and GIS analysts rely on UTM for metric accuracy over regional extents. This converter implements the WGS84 ellipsoid formulas to produce precise easting/northing pairs.
Results are suitable for mapping applications, CAD imports, or as a quick check against field instrument outputs.
Combine with the Coordinates Converter for formatting or the Scale Calculator when moving between map and ground measurements.
Frequently Asked Questions
What latitude range does UTM support?
Standard UTM zones cover latitudes between 80°S and 84°N. Inputs outside this range are clamped to maintain accuracy.
Do I need to enter degrees-minutes-seconds?
No. Enter decimal degrees. Use the Degrees Minutes Seconds Calculator if you need to convert from DMS first.
What datum is used?
The converter assumes the WGS84 datum, matching GPS coordinates. For NAD83 or other datums, transform coordinates before use.
Can I convert UTM back to lat/long?
Not in this tool. Consider adding a UTM to Lat/Long converter or use GIS software for the inverse transformation.
