HowHow it works

Coordinate converter, step by step

  1. Step 1

    Paste anything

    Type or paste a coordinate in decimal degrees, DMS, UTM, Web Mercator metres or geohash. The tool detects the format as you type; a toggle disambiguates lat,lng from lng,lat.

  2. Step 2

    Or click the map

    Drop a pin by clicking, or drag it to fine-tune. The pin and every output stay in sync.

  3. Step 3

    Convert in bulk

    Switch to batch mode, paste many lines, and download a CSV with every format. Open a single point in the studio to build from it.

Your data never leaves the page

Every conversion, measurement and export happens client-side. Nothing is uploaded, logged or stored — you can even use this offline once the page has loaded. Only “Open in Studio” sends data, and only after you sign in.

FAQQuestions

Good to know

Which coordinate formats does it read?
Decimal degrees ("41.0082, 28.9784"), degrees-minutes-seconds (41°0'29"N 28°58'42"E), UTM (35T 660000 4543000), Web Mercator / EPSG:3857 metres, and geohash. It auto-detects the format as you type; a toggle disambiguates lat,lng from lng,lat for plain decimal pairs.
How accurate is the UTM conversion?
UTM uses proj4 with the WGS84 ellipsoid and the correct zone/hemisphere, so it round-trips to sub-millimetre precision. The zone is inferred from the longitude, or you can state it explicitly (e.g. 35T).
Can I convert many coordinates at once?
Yes. Switch to batch mode, paste one coordinate per line, and the tool builds a table with every format and a Download CSV button. Mixed input formats in one list are fine.
What is a geohash?
A geohash encodes a latitude/longitude into a short string where nearby places share a prefix. The converter encodes to and decodes from geohash and shows the cell the hash represents on the map.
Is my location sent anywhere?
No. Every conversion is pure client-side maths. Nothing is uploaded unless you choose Open in Studio after signing in.
