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.
Hectares
A hectare is a unit of area measurement equal to 10,000 square meters or 100 ares. It is commonly used in agriculture, forestry, and land management to measure large plots of land. Hectares are particularly significant in countries that use the metric system, as they provide a convenient way to quantify large land areas for farming, conservation, and property transactions. One hectare is roughly equivalent to 2.47 acres.
