What is the primary unit of measurement in the UTM coordinate system?

The primary unit of measurement in the Universal Transverse Mercator (UTM) coordinate system is meters. The UTM system divides the world into a series of longitudinal zones, each of which is measured in meters, providing a consistent and standardized way to represent locations on the Earth's surface. Meters are used because they allow for easier calculations and interoperability with other metric systems, which is essential in scientific and professional applications such as mapping and geographic information systems. This makes the UTM system particularly useful for mapping over large areas, as it provides high accuracy in spatial measurements.
