Common GPS Coordinate Conversion Examples
Reference examples for popular coordinate conversions used in GPS, GIS, surveying, and map workflows.
DD to DMS Conversion
Multiply the decimal part by 60 to get minutes, then multiply fractional minutes by 60 for seconds. Add N/S and E/W direction.
40.7128 to 40d 42m 46s N UTM to Lat/Long
Identify UTM zone number and letter, then apply inverse Transverse Mercator projection to get geographic coordinates.

dr5regw3pg to 40.7128N, 74.0060W Frequently Asked Questions
Common questions about coordinate formats, accuracy, datums, privacy, and browser-based GPS conversion workflows.
What is a coordinate converter?
A tool that transforms geographic coordinates between different formats such as Decimal Degrees, DMS, DDM, UTM, MGRS, Plus Code, and Geohash. All processing happens instantly in the browser with live map preview.
How accurate is this converter?
It delivers up to 6 decimal places of precision (about ±0.11 meters), which meets the needs of most GPS, GIS, surveying, drone, and hiking applications.
Is my coordinate data private and secure?
Yes — core conversions run locally in your browser using Web Workers. We do not store or log your coordinate data on our servers.
What coordinate formats are supported?
Seven major formats are fully supported: Decimal Degrees, DMS, DDM, UTM, MGRS, Plus Code, and Geohash. All conversions are bidirectional and work instantly.
What is the difference between DD, DMS, and DDM?
These are three common ways to write the same latitude and longitude. Decimal Degrees uses pure numbers, DMS uses degrees-minutes-seconds, and DDM uses degrees plus decimal minutes.
What is UTM and when should I use it?
UTM is a zone-based meter grid system ideal for surveying, engineering projects, and precise topographic mapping.
What is MGRS and who uses it?
MGRS is a compact alphanumeric grid based on UTM, commonly used in military operations, emergency response, and outdoor navigation.
Do I need to create an account?
No account is ever required. The entire coordinate conversion process runs directly in your browser with zero data upload.
Can I convert multiple coordinates at once?
Yes. Switch to the dedicated Batch Coordinate Converter to handle CSV files, pasted tables, or hundreds of rows in a single workflow.
What datum does this converter use?
All conversions are performed on the global WGS84 datum, the same standard used by GPS satellites and major mapping platforms.
Why do GPS coordinates show offset on Chinese maps?
Chinese mapping products (Gaode, Baidu, Tencent) may use GCJ-02 or BD-09 instead of standard WGS84 coordinates. Please use our GCJ02 to WGS84/BD09 tool for coordinate conversion before displaying on the map.
What is the difference between WGS84 and NAD83?
WGS84 and NAD83 are two geodetic datums with only minor differences for most practical GPS and mapping uses.
