This free coordinate converter translates between decimal degrees (DD), degrees minutes seconds (DMS), degrees decimal minutes (DDM), UTM, and MGRS — all at once. Enter coordinates in any format and press its Convert button, or click anywhere on the map, search an address, or use your current location: every format updates instantly, with a marker showing the point. All conversions run in your browser on the WGS84 datum, and each format has a one-click Copy button.

How do I convert DMS to decimal degrees?

Enter the degrees, minutes, and seconds with the N/S or E/W hemisphere and press Convert from DMS. The formula is degrees + minutes/60 + seconds/3600, negative for south latitudes and west longitudes — the converter does this for you and shows the result in every other format too.

How do I convert UTM to latitude and longitude?

Enter the UTM zone number (1–60), hemisphere, easting, and northing, then press Convert from UTM. The point appears on the map with its latitude and longitude in decimal degrees, DMS, and DDM. Conversions use the WGS84 datum.

What is an MGRS coordinate?

The Military Grid Reference System (MGRS) is a compact grid format built on UTM, used by NATO militaries and many emergency services — for example 18TWL8074204692. Paste any MGRS reference to see its location, or click the map to get the MGRS reference for any point at 1-meter precision.

Which datum does the converter use?

All conversions use WGS84, the datum used by GPS and by Google Maps. If your source data uses a different datum (such as NAD27), convert it to WGS84 first — positions can differ by up to a few hundred meters between datums.

How do I find the coordinates of a place?

Search for the address or place name, or just click the map — the marker shows the spot and every coordinate format fills in automatically. Drag the marker to fine-tune the position, and use Copy Link to share the point.
