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 inch (in²) is commonly used in the United States for small surface measurements. A standard post-it note is about 6 in², while a sheet of letter-sized paper is 93.5 in². This unit is prevalent in printing, crafts, and engineering drawings.
To convert between Square Kilometer (km²) and Square Inch (in²), use the following formulas:
1 Square Kilometer (km²) = 1550003100.0062 Square Inch (in²)
1 Square Inch (in²) = 6.4516e-10 Square Kilometer (km²)
1 km² = 1 * 1550003100.0062 in² = 1550003100.0062 in²
5 km² = 5 * 1550003100.0062 in² = 7750015500.031 in²
10 km² = 10 * 1550003100.0062 in² = 15500031000.062 in²
100 km² = 100 * 1550003100.0062 in² = 155000310000.62 in²
