About Square Kilometers
A square kilometer (km²) is a metric unit of area equal to a square with sides of one kilometer (1,000 m × 1,000 m). It is used for measuring large land areas such as cities, forests, lakes, and countries. Manhattan (New York) is about 59 km², and Monaco (the second smallest country) is just over 2 km². This unit is essential in geography, urban planning, forestry, and environmental impact studies.
