DMS Coordinate Converter
Convert latitude/longitude between decimal degrees and degrees-minutes-seconds
About this calculator
The DMS Coordinate Converter translates latitude and longitude between signed decimal degrees and degrees-minutes-seconds. It accepts flexible input — plain decimals, hemisphere suffixes like 40.4461 N, or DMS forms such as 40°26′46″ N or 40 26 46 N — and returns decimal degrees, formatted DMS, and degrees-decimal-minutes for both axes. Latitude is validated to ±90° and longitude to ±180°, with separate errors for out-of-range and unparseable input.

Frequently asked questions
How does the DMS Coordinate Converter calculator work?
Enter your numbers and the calculator applies the standard formula for this everyday task, showing the result and how it was reached. It handles the unit and rounding details so you do not have to.

Whenever this comes up in daily life — planning, shopping, home projects, travel or work — and you want a quick, dependable answer instead of estimating or working it out by hand.
How accurate are the results?
The math runs at full precision internally and only the displayed value is rounded for readability. For real-world use the practical limit is the accuracy of the numbers you enter, not the calculation.
Can I share a specific calculation with someone else?
Yes. Every value you enter updates the URL, so copying the address bar and sharing the link reopens the exact same calculation for whoever clicks it.
