Decimal Degrees to DMS Converter
Convert coordinates between decimal degrees (DD) and degrees-minutes-seconds (DMS) in either direction — useful for GPS coordinates, surveying, and navigation.
Inputs explained
- Conversion direction — Decimal degrees to DMS, or DMS to decimal degrees.
- Decimal degrees — The angle in decimal form, e.g. 45.5. Negative values keep their sign.
- Degrees — The whole-degree part (DMS input).
- Minutes — Arc-minutes, 0–59 (DMS input).
- Seconds — Arc-seconds, 0–60 (DMS input).

Understanding the result
Example: 45.5° equals 45° 30′ 0″ in degrees-minutes-seconds.
Frequently asked questions
Why do minutes and seconds only go up to 59? Because a degree is divided into 60 minutes and each minute into 60 seconds, so any remainder of 60 or more is carried over into the next larger unit before the result is displayed.
Does the sign (N/S/E/W or negative) get handled correctly when converting? Only the numeric magnitude is converted between decimal degrees and DMS; if your coordinate is negative or has a hemisphere letter, you should track that sign separately since the conversion works on the absolute value.
