The square kilometer (km²) measures large territories and geographic areas. Central Park in New York covers 3.41 km², while Paris occupies about 105 km². This unit is essential for urban planning, environmental studies, and country-size comparisons. The square centimeter (cm²) is commonly used for small everyday objects. A standard postage stamp measures about 4 cm², while a smartphone screen ranges from 80-120 cm². This unit is particularly useful in medical imaging (tumor sizes) and school science projects.
To convert between Square Kilometer (km²) and Square Centimeter (cm²), use the following formulas:
1 Square Kilometer (km²) = 10000000000 Square Centimeter (cm²)
1 Square Centimeter (cm²) = 1e-10 Square Kilometer (km²)
1 km² = 1 * 10000000000 cm² = 10000000000 cm²
5 km² = 5 * 10000000000 cm² = 50000000000 cm²
10 km² = 10 * 10000000000 cm² = 100000000000 cm²
100 km² = 100 * 10000000000 cm² = 1000000000000 cm²
