Decimal to DMS converter
Convert decimal GPS coordinates to degrees, minutes and seconds.
How to use
- Paste decimal coordinates as "latitude, longitude" — e.g. -6.2088, 106.8456 — one pair per line.
- The DMS form appears instantly, hemispheres (N/S/E/W) derived from the signs.
- Copy the result for your chart, document or report.
Frequently asked questions
Which number is latitude and which is longitude?
Latitude comes first (north–south, −90 to 90), longitude second (east–west, −180 to 180). Jakarta is -6.2088, 106.8456 — south of the equator, east of Greenwich.
How precise is one decimal of a second?
About 3 meters of ground distance — more precise than a phone GPS fix, so nothing meaningful is lost in conversion.
Why did my coordinate get rejected?
Latitude must be between −90 and 90 and longitude between −180 and 180; the offending line is shown so you can fix a swapped pair.
About this tool
GPS devices, phone apps and mapping APIs hand you coordinates as decimal degrees (-6.2088, 106.8456), but nautical charts, surveying documents, land certificates and aviation notation still speak degrees-minutes-seconds (6°12'31.7"S 106°50'44.2"E). This converter translates from decimal to DMS with the hemisphere letters worked out from the signs — negative latitude becomes S, negative longitude W. Paste one coordinate pair per line to convert a whole list, such as a route export or survey table. Seconds are rounded to one decimal place, which corresponds to roughly three meters of precision — finer than consumer GPS itself.
