WGS84 to UTM converter

About This Tool

This tool converts geographic coordinates from WGS84 to the UTM projection, returning easting, northing, zone, and hemisphere. It accepts latitude and longitude in decimal degrees and can auto-derive the appropriate UTM zone or use a user-specified zone. Outputs are in meters and suitable for GIS datasets and mapping tasks. The tool is designed for GIS analysts, surveyors, field engineers, and researchers who need consistent projected coordinates for analysis, data integration, and cartographic production.\n\nConceptually, the conversion follows the standard WGS84 to UTM method: determine the UTM zone, compute the central meridian, apply the transverse Mercator projection with the scale factor, and add the false easting to produce easting and northing. The process yields zone like 11N for Los Angeles lat/lon and ensures coordinates are compatible with common GIS projections. The tool supports both automatic zone calculation and explicit zone specification to accommodate datasets with known zones.\n\nCore value: accuracy, consistency, and interoperability across GIS platforms. Use cases include converting GPS logs, transforming shapefile coordinates for display, validating coordinate data, and preparing datasets for spatial analysis. Unique differentiators include robust input validation, explicit handling of southern/northern hemisphere, and automatic zone determination to reduce manual steps. Example input lat=34.05, lon=-118.25 yields UTM coordinates in the appropriate zone for Los Angeles.
