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.
To convert between Square Kilometer (km²) and Acre (ac), use the following formulas:
1 Square Kilometer (km²) = 247.10516301527602 Acre (ac)
1 Acre (ac) = 0.00404686 Square Kilometer (km²)
1 km² = 1 * 247.10516301527602 ac = 247.10516301527602 ac
5 km² = 5 * 247.10516301527602 ac = 1235.52581507638 ac
10 km² = 10 * 247.10516301527602 ac = 2471.05163015276 ac
100 km² = 100 * 247.10516301527602 ac = 24710.5163015276 ac
