About Coordinate Conversion

Coordinates are essential for locating points on Earth's surface. The most common format is decimal degrees, where latitude ranges from -90° to +90° and longitude ranges from -180° to +180°. This system is used by GPS devices and most modern mapping applications.

The traditional Degrees, Minutes, Seconds (DMS) format provides more precise angular measurements. One degree equals 60 minutes, and one minute equals 60 seconds. This format is still used in surveying, navigation, and some mapping applications where high precision is required.

Grid-based coordinate systems like UTM (Universal Transverse Mercator) and MGRS (Military Grid Reference System) provide local coordinate references that are easier to use for navigation and tactical operations. These systems divide the Earth into zones and use metric measurements for distance calculations, making them ideal for field applications.
