Coordinate Converter
Paste coordinates in any common format — decimal degrees (40.446111, -79.982222), degrees-minutes-seconds (40°26'46"N 79°58'56"W), degrees decimal minutes, or UTM (31 N 448251 5411932) — and get all four representations at once, ready to copy.
The input format is detected automatically, or you can pick it explicitly with the format selector. Hemisphere letters may come before or after the numbers, and : or spaces work as separators.
UTM conversion uses the WGS-84 ellipsoid, including the standard Norway and Svalbard zone exceptions, with accuracy far beyond a millimeter. Latitudes above 84°N or below 80°S fall outside UTM coverage and are left blank.
Notes
- Decimal degrees (DD) —
40.446111, -79.982222, six decimal places (~0.1 m). - Degrees-minutes-seconds (DMS) — degrees, whole minutes, seconds to two decimals.
- Degrees decimal minutes (DDM) — degrees plus decimal minutes, the default on most GPS devices.
- UTM — zone, hemisphere, easting and northing to the whole meter.
