Q:How do I convert decimal degrees to DMS?
Enter your decimal degree coordinates (e.g., 40.7128, -74.0060) in the input box and select DMS as the output format. The tool instantly converts and displays degrees, minutes, and seconds (e.g., 40°42'46'' N, 74°0'21'' W).
Q:Can I bulk-convert a CSV file of coordinates?
Yes. Upload a CSV with a latitude and longitude column and choose your target format. The tool converts all rows at once and lets you download the results as a new CSV.
Q:What coordinate systems does it support?
Decimal Degrees (DD), Degrees Minutes Seconds (DMS), Degrees Decimal Minutes (DDM), UTM (Universal Transverse Mercator), MGRS (Military Grid Reference System), and ECEF (Cartesian XYZ).
Q:Is Coordinate Converter free?
Yes, completely free with no account required.
Q:Does it upload my data to a server?
No. All coordinate math runs locally in your browser using proj4.js. No data is sent to any server.
Q:Which datum does it use?
WGS84 is the primary datum. This is the same datum used by GPS devices and Google Maps, so results are directly compatible.
Q:What coordinate formats does this tool convert between?
The tool converts between Decimal Degrees (DD), Degrees Minutes Seconds (DMS), Degrees Decimal Minutes (DDM), UTM (Universal Transverse Mercator), and MGRS (Military Grid Reference System). All conversions are bidirectional.
Q:What datum is used for conversions?
WGS84 is the default datum, which is the standard used by GPS devices, Google Earth, and most modern GIS software. This is the same as the EPSG:4326 coordinate reference system.
Q:Can I batch convert hundreds of coordinates?
Yes. Upload a CSV file with your coordinates and select the input format. The tool converts every row and lets you download the enriched CSV with all formats added as new columns.
Q:Is my data uploaded to your servers?
No. All coordinate math runs locally in your browser. No coordinates or files are sent to any server.
Q:What is the difference between UTM and MGRS?
Both use a grid system based on metres. UTM gives you a zone number, letter, and X/Y easting/northing values (e.g., 37N 234567 3456789). MGRS is a military format that encodes the same location as a compact alphanumeric code used by NATO forces (e.g., 37TEK3456789).
