Square Kilometer

A square kilometer (km²) is a large metric unit used to measure wide geographic areas. One km² equals one million square meters, making it perfect for cities, forests, lakes, and regions. It is widely used in maps, environmental studies, and land-use planning.

This scale helps governments, scientists, and researchers describe the size of natural and urban spaces with clarity. Converting km² into acres or square miles provides helpful context across measurement systems.

Square Kilometers in Geography

Comparisons of countries, national parks, farmland, and natural habitats frequently use km² for easy communication. Population density — people per km² — is also a standard reference in demographics.

For everyday understanding, a converter can translate square kilometers into units familiar to homeowners or travelers, improving practical context.
