Lat/Long to UTM Approximation

°
°
Conversion

Approximate conversion from geographic coordinates (WGS84) to UTM zone and easting/northing.

Formula

UTM Zone = floor((lon + 180) / 6) + 1; Transverse Mercator projection (WGS84)
  • Approximate — not suitable for geodetic surveying. Uses WGS84 ellipsoid.
  • For precise conversion use a dedicated GIS library.
