Open GPSwitch ConverterMGRS (Military Grid Reference System) is the NATO standard for expressing geographic positions as a compact alphanumeric string. It is used by military forces, emergency services, search and rescue teams, and GIS professionals who work with defence mapping data.
The key advantage of MGRS over decimal coordinates is readability and error resistance on radio communications. A grid reference like 31UDQ 48251 12678 is easier to read over voice than "48.8583 degrees North, 2.2944 degrees East".
For 48.8583°N, 2.2944°E, the MGRS reference is 31UDQ 48251 12678:
GPSwitch outputs MGRS at 1-metre precision (5+5 digit pairs) by default when you provide decimal coordinates with 4 or more decimal places. Lower-precision coordinates produce lower-precision MGRS output.
Yes. MGRS is the NATO Military Grid Reference System. The US military also uses USNG (US National Grid) which is identical to MGRS for most practical purposes. GPSwitch handles both.
Yes. GPSwitch converts in both directions. Paste an MGRS reference and get decimal lat/long, DMS, UTM, Geohash, and navigation links in one step.
