How to use

About this tool

This coordinate converter transforms locations between decimal degrees, DMS, DMM, UTM, MGRS, and Geohash. It is built for GIS development, cartography, field work, and any workflow where you must unify position formats. Paste one or more coordinates, choose the output format, and check the result. It supports batch conversion and offers a map preview so you can verify the converted point lands where you expect. The tool is free, requires no signup, and works in the browser. Use it to validate GPS data, prepare map inputs, or review coordinates before integrating them into an app.

How to use

① Enter coordinates one per line (paste or load from file). Use the clear button to reset. ② Results are shown automatically with all 6 formats per line. ③ The "Map Preview" below displays markers for converted coordinates. The map is visible from the start and can be panned/zoomed. Click a marker for a popup. With multiple coordinates, the map auto-zooms. Empty lines are ignored.

Use cases

• Converting formats for maps and GIS • Switching between lat/lon, UTM, MGRS and Geohash • Batch conversion and map visualization of coordinates • Normalizing mixed-format coordinate lists

Privacy and data

All conversion runs in the browser; no coordinate data is sent to any server.
