⚠️ Datum Hazard: Read Before Conversion

Coordinate values only have meaning when attached to a Datum.

  • WGS84: Standard for GPS, Google Maps, Web Mercator.
  • NAD27: Used in older USGS topographic maps (pre-1983).

Using the wrong datum can shift your position by 20-100+ meters. Always verify the source datum of your coordinates.

FAQ

Q: What is MGRS?

A: MGRS stands for Military Grid Reference System. It is a geocoordinate standard used by NATO militaries for locating points on the earth. It is derived from the UTM (Universal Transverse Mercator) grid system and UPS (Universal Polar Stereographic) grid system, but uses a different labeling convention.

Q: Is this tool accurate?

A: Yes, it uses standard MGRS conversion algorithms based on the WGS84 datum. However, always verify critical coordinates with multiple sources if safety is at risk.

Q: Can I convert batch coordinates?

A: Currently, this tool supports single coordinate conversion. For batch processing, please contact us or check our upcoming features.
