The acre is the standard unit for land measurement in the US and UK. A football field (including end zones) is about 1.32 acres, while a small farm might be 10 acres. This unit is essential for agriculture, real estate, and land development projects. 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.
To convert between Acre (ac) and Square Kilometer (km²), use the following formulas:
1 Acre (ac) = 0.00404686 Square Kilometer (km²)
1 Square Kilometer (km²) = 247.10516301527602 Acre (ac)
0.25 ac = 0.25 * 0.00404686 km² = 0.001011715 km²
1 ac = 1 * 0.00404686 km² = 0.00404686 km²
5 ac = 5 * 0.00404686 km² = 0.0202343 km²
10 ac = 10 * 0.00404686 km² = 0.0404686 km²
