GPS Coordinate Converter
Convert GPS coordinates between decimal and DMS.
Decimal degrees and DMS
The same location can be written as decimal degrees (40.7128) or degrees-minutes-seconds (40°42′46″N), and mapping tools disagree about which they want. This converts cleanly between the two.
It resolves the common headache of pasting coordinates between apps — a phone might give decimal degrees while a marine chart or older GIS tool expects degrees, minutes, and seconds.
Sign and hemisphere
Negative decimals mean south or west, which becomes the N/S/E/W letter in DMS. All conversion runs in your browser and nothing is uploaded. Your coordinates are converted locally and never uploaded.
Frequently Asked Questions
How does the gps coordinate converter work?
Decimal degrees convert to degrees, minutes, and seconds by separating whole degrees, multiplying the remainder by 60, then repeating for seconds.
When should I use this tool?
Use it for maps, geotagging, field notes, drone logs, and converting coordinates between apps.
What is the main limitation?
The tool converts formats only; it does not geocode addresses or verify that a coordinate is on land.
Is this converter private?
Yes. It runs entirely in your browser, so your values are not uploaded or stored.
