Coordinate converter
Convert latitude and longitude between decimal degrees and degrees–minutes–seconds (DMS), copy the result, and open it straight in Google Maps or OpenStreetMap.
Everything is WGS84 (the GPS datum), computed in your browser — nothing is uploaded. There is also an optional haversine distance-and-bearing tool between any two points.
Coordinates
Use negatives for South / West, e.g. −27.5. Latitude −90…90, longitude −180…180.

Decimal degrees and DMS, both ways
The same point on Earth can be written two ways. Converting between them is just splitting (or recombining) the fractional part of a degree into minutes and seconds.
Degrees → DMS
Whole part = degrees. The decimal × 60 gives minutes; that remainder × 60 gives seconds.
DMS → degrees
degrees + minutes ÷ 60 + seconds ÷ 3600, with a minus sign for the South or West hemisphere.
WGS84 throughout
The output is EPSG:4326 lat/long — paste it directly into GPS units, Google Maps or OpenStreetMap.
Coordinate conversion, answered
How do I convert decimal degrees to degrees, minutes and seconds?+
Take the whole-number part as the degrees. Multiply the remaining decimal by 60 — the whole part is the minutes. Multiply that remainder by 60 again to get the seconds. The sign decides the hemisphere: positive latitude is North, negative is South; positive longitude is East, negative is West. This converter does all of that instantly.
How do I convert DMS back to decimal degrees?+
Decimal degrees = degrees + minutes ÷ 60 + seconds ÷ 3600, then made negative if the hemisphere is South or West. For example 27° 43′ 01.92″ N is 27 + 43/60 + 1.92/3600 = 27.7172°.
How many decimal places do I need for coordinates?+
Six decimal places of a degree is about 0.11 metres at the equator — far more than a phone GPS can resolve. Five places (~1.1 m) is plenty for most mapping, and four (~11 m) is fine for a town or village.
How is the distance between two coordinates calculated?+
This tool uses the haversine formula — the great-circle distance on a sphere of mean radius 6,371 km — and reports the initial compass bearing. Across distances within Nepal the spherical assumption is accurate to well within half a percent.
Are these coordinates in the WGS84 datum?+
Yes. Decimal-degree and DMS latitude/longitude here are WGS84 (EPSG:4326) — the same datum used by GPS, Google Maps and OpenStreetMap — so you can paste the output straight into those services.
Sources & data note
Latitude and longitude here use the WGS84 datum (EPSG:4326). Distance and bearing use the haversine great-circle formula on a mean Earth radius of 6,371 km. All computation runs locally in your browser.
