Square Foot
A square foot (ft2) is a unit of area measurement equal to the area of a square with sides one foot in length. It is commonly used in the United States, Canada, and the United Kingdom to measure smaller areas such as the size of rooms, apartments, or other building spaces. Square feet are essential in real estate, interior design, and construction, providing a standard measure for comparing and planning spaces.
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.
