Square Kilometers
A square kilometer (km2) is a unit of area measurement equal to one million square meters or the area of a square with sides one kilometer long. It is commonly used to measure large areas such as cities, regions, and natural landscapes. Square kilometers are crucial in geography, urban planning, and environmental studies, helping to quantify and compare vast tracts of land or water, such as forests, lakes, and entire countries.
Square Miles
A square mile (mi2) is a unit of area measurement equal to the area of a square with sides one mile in length, or 640 acres. It is commonly used to measure large land areas, such as cities, counties, or natural landscapes. Square miles are important in geography, urban planning, and environmental studies, helping to quantify and compare the vast extents of regions, national parks, and entire states or countries.
