Convert geographic coordinates between Decimal Degrees (DD), Degrees Minutes Seconds (DMS), Degrees Decimal Minutes (DDM), and UTM (Universal Transverse Mercator). Uses the full Karney/Krüger ellipsoidal transverse Mercator series on the WGS84 ellipsoid for millimeter-level UTM accuracy, not a spherical approximation.
This tool provides precise conversions between Decimal Degrees, DMS, DDM, and UTM formats using the WGS84 ellipsoid. It eliminates the need for desktop GIS software or manual calculations for standard coordinate transformation tasks. Being entirely web-based, it offers quick access without requiring installation or account creation.
Good to know: Users requiring bulk batch conversions of thousands of coordinates or operations outside the WGS84 datum may need specialized GIS software or custom scripting.
Quickly convert geographic coordinates between DD, DMS, DDM, and UTM formats with high precision.
