How to Use This Calculator
  1. Select the Conversion Direction: Lat/Lon → UTM or UTM → Lat/Lon.
  2. For Lat/Lon → UTM, enter the Latitude and Longitude in decimal degrees.
  3. For UTM → Lat/Lon, enter the UTM Easting, Northing, and Zone.
  4. Review the converted Latitude and Longitude (in decimal degrees and DMS) or the converted UTM Easting, Northing, and Zone.
  5. All conversions use the WGS84 datum.

What each input means

Conversion Direction
Select the conversion direction.
Latitude
Latitude in decimal degrees (positive = North, negative = South).
Longitude
Longitude in decimal degrees (positive = East, negative = West).
UTM Easting
UTM easting coordinate in meters.
UTM Northing
UTM northing coordinate in meters.
UTM Zone
UTM zone number (1-60).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Conversion Direction = 1, Latitude = 40, Longitude = -105, UTM Easting = 500000 = 6 input(s) provided
  2. Calculate UTM Easting
    UTM Easting
    500000 = 500000
  3. Calculate UTM Northing
    UTM Northing
    4427757.22 = 4427757.22
  4. Calculate Latitude
    Latitude
    40 = 40
  5. Calculate Longitude
    Longitude
    -105 = -105
