How to use Geographic Coordinate Converter

The Geographic Coordinate Converter switches between decimal degrees, degrees minutes seconds and UTM formats. Enter coordinates in one format, choose the target format, and the converted values appear instantly. It is essential for GPS devices, mapping software and field survey work.


How to use this tool

  1. Enter the coordinates in the source format.
  2. Select the source coordinate format.
  3. Select the target format.
  4. View the converted coordinates.

When to use this tool

  • Plugging coordinates into a mapping app that expects a specific format.
  • Sharing GPS waypoints with teams using different devices.
  • Converting survey data between UTM and latitude-longitude.
  • Standardizing location data for databases and reports.

Practical examples

The coordinate 40.7128 degrees latitude equals 40 degrees 42 minutes 46.08 seconds in DMS. Entering 40.7128 with decimal degrees as the source and DMS as the target returns the degrees, minutes and seconds used by many GPS units.


Tips for accurate results

  • Watch the sign of latitude and longitude to keep north, south, east and west correct.
  • Keep enough decimal places to preserve accuracy for your use case.
  • Confirm the target format your app expects before converting.

Frequently asked questions

Which coordinate formats are supported?

Will converting reduce accuracy?

No, the math is exact. Accuracy loss only comes from rounding, so keep enough decimal places.

Can I convert multiple points at once?

This tool converts one coordinate at a time. Convert each point separately for a set.
