About the Coordinate Format Converter Online Free Tool

The Coordinate Format Converter Online Free Tool converts between decimal degrees and degrees-minutes-seconds coordinate text.

How to Use the Coordinate Format Converter Online

1. Select decimal-to-DMS or DMS-to-decimal mode.
2. Enter coordinates in the active input fields.
3. Run the converter to review the converted coordinate format.

Choosing Options Correctly

Use signed decimal degrees for decimal input. For DMS input, include degrees, minutes, seconds, and direction consistently so west/south values become negative.

Common Use Cases

• Convert survey coordinates for reports.
• Prepare GPS values for mapping software.
• Translate DMS coordinates into decimal GIS values.

Quick FAQ

Can I paste mixed formats?
No. Use the fields for the selected mode so the parser knows how to read the coordinates.

Which sign convention is used?
North and east are positive; south and west are negative.

What causes wrong map results?
Most errors come from mixing coordinate formats, swapping latitude and longitude, or assuming the wrong coordinate reference system.

Does this transform datums?
No. It converts coordinate notation; datum transformations need a proper CRS transformation workflow.
