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 Millimeters
A square millimeter (mm2) is a unit of area measurement equal to the area of a square with sides that are one millimeter in length. This tiny unit of area is often used in precision engineering, electronics, and materials science, where very small surface areas need to be measured accurately. Square millimeters are essential for detailing the dimensions of microchips, small mechanical parts, or any other objects where precision is crucial.
