Lat lon to MGRS
The Military Grid Reference System turns a WGS84 latitude and longitude into a compact alphanumeric grid string used on topographic maps, land navigation courses, and many defense and emergency workflows.
Run — free
Runs in your browser. Free, unlimited — your data never leaves this page.
This capability projects your coordinates with standard UTM between eighty degrees south and eighty-four degrees north, or UPS in the polar caps, then attaches the grid-zone designator, the two-letter one-hundred-kilometer square, and a truncated numerical easting and northing at the precision you choose from zero through five digits. Students, GIS engineers, and backend services get deterministic JSON they can pin in tests without embedding a full GeoTrans stack. Precision above five digits or coordinates outside the valid latitude and longitude ranges fail with a clear invalid input error. The browser widget runs free on your device; the prepaid API charges $0.002 per successful item when you need the same contract from servers and SDKs.
How to use it
Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.
Check your inputs
Use the labels and units shown next to each field. If something is missing or outside the allowed range, the page points to the field to fix.
Use it again or automate it
Use the browser tool for individual checks and the API when you need the same capability in an automated workflow.
What you can do with it
Get an answer now
Enter one set of values and see the result without building a spreadsheet or script.
Compare scenarios
Change one value at a time and rerun the calculation to understand what affects the result.
Automate repeated work
Use the API when the same calculation needs to run inside your product or workflow.
FAQ
How do I use this capability?
Complete the fields above and run it on this page. The form highlights anything that needs attention.
For developers — API access
Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.
API endpoint
Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

}The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.
Pricing
Published price — no tokens, no invented credits. A failed task is never charged.
