GPS Coordinates Converter
Convert
Paste a coordinate in any common format — decimal pair (40.7128, -74.0060), DMS (40°42'46"N 74°00'21"W), or DMM (40°42.766'N 74°00.35'W) — and see all three side by side. Also produces a `geo:` URI for mobile mapping apps and a Google Maps link you can open directly. Hemisphere markers (N/S/E/W) are inferred from sign for decimal inputs and respected for DMS/DMM.

Google Maps
Open →Decimal uses latitude first (negatives = South/West). DMS and DMM use N/S/E/W markers.
How to use
- Paste your coordinate in any supported format.
- Read off decimal, DMS, and DMM equivalents.
- Copy the format you need or click the Google Maps link to verify the location.
Frequently asked questions
- Which lat/lon order should I use?
- Latitude first, then longitude — both this tool and most APIs (Google Maps, Geo URI) use that order. GeoJSON is the famous exception (it's lon, lat) — don't paste GeoJSON coordinates directly.
- What hemisphere is `-40.7128`?
- Negative latitude is South, negative longitude is West. So `-40.7128, -74.0060` reads as 40.7128°S, 74.0060°W. DMS notation uses explicit N/S/E/W suffixes instead.
- How precise are these?
- Decimal at 6 decimal places resolves to about 11 cm. DMS at 2 decimal places on seconds is about 30 cm. Either is far more precise than civilian GPS (~3–5 m), so the limit is your measurement, not the format.
- Does the Google Maps link reveal my location?
- Only when you click it, and only to Google — not to this site. The coordinate is in the URL itself; opening the link in your browser is the same as typing it into Maps.
