Square Centimeter (cm²)
Definition: A square centimeter (symbol: cm²) is a metric unit of area equal to a square measuring 1 centimeter on each side. One square centimeter equals 0.0001 square meters or approximately 0.155 square inches.
History: Created as part of the metric system's coherent decimal structure, providing a practical unit between the square meter (too large) and square millimeter (too small) for everyday measurements. Its definition is derived directly from the meter's definition.
Current use: Widely used in engineering drawings, medical imaging (tumor sizes), and for measuring small surfaces like electronic components. Common in countries using the metric system for everyday measurements of small objects.
Square Kilometer (km²)
Definition: A square kilometer (symbol: km²) is a multiple of the square meter, equal to the area of a square with 1 kilometer (1000 meters) on each side. One square kilometer equals 1,000,000 square meters or approximately 0.3861 square miles.
History: Developed as part of the metric system's decimal-based scaling, the square kilometer became particularly useful for geographical measurements. Its adoption grew with the metric system's international acceptance in the 19th and 20th centuries.
Current use: Primarily used to measure large land areas such as cities, national parks, and countries. Commonly appears in geographical surveys, urban planning, and environmental studies. Most world maps and atlases use square kilometers, though some US publications still use square miles.
