Coordinate converter

Paste a coordinate in any notation — decimal degrees, DMS, even a place’s lat/long — and instantly get every common format back, with a live map and one-tap copy. Everything runs in your browser.

What is a coordinate converter?

A coordinate converter changes a single geographic point between the notations people and systems use to write it — decimal degrees (DD), degrees-minutes-seconds (DMS), degrees-decimal-minutes (DDM), UTM, MGRS, Plus Codes and Geohash. They all describe the same spot on Earth; only the formatting differs.

How to convert coordinates

  1. Type or paste a coordinate in any supported format into the box above (or use your current location).
  2. Read the converted value in every other format underneath — they update as you type.
  3. Tap the copy button next to the format you need, or open the point on a map.

Is it accurate and private?

Yes. The conversions are exact mathematical transforms on the WGS84 datum and run entirely in your browser — nothing is uploaded. Decimal degrees to six places resolve to about 11 cm.

Frequently asked questions

What is the difference between DD, DMS and DDM?

Decimal degrees (DD) writes a coordinate as one number, e.g. 40.7128. DMS splits it into 40°42′46″, and DDM uses 40°42.767′. They are three notations for the same point. Use the DMS to decimal or decimal to DMS tools for those two directly.

What are UTM and MGRS?

UTM (Universal Transverse Mercator) gives a zone plus easting/northing in meters; MGRS adds a 100 km grid-square letter pair. Both are popular in surveying and the military. See lat/long to UTM and lat/long to MGRS.

Is this coordinate converter free?

Yes — it’s completely free, needs no account, and runs entirely in your browser. Your coordinates are never sent to a server.

Which format should I use?

Decimal degrees for apps, links and code; DMS for paper maps and charts; UTM/MGRS for surveying or field work; Plus Codes to share a spot that has no street address.
