Area unit conversion, the original unit is square kilometers, the target unit is hectares, and the decimal unit is 100. Calculate 1 km2 equals how many hectares are needed 1× 100, and the result is 100. Therefore, 1 km2 is equal to 100 hectare. Area unit conversion, the original unit is square kilometers, the target unit is square meters, and the decimal system is 100000. To calculate how many square meters 1× 1000000, you need 1000000, and the result is equal to 1000000. So 1 square kilometer equals 65438.

1 km2 = 100 hectares = 1000000 square meters. Square kilometer is the metric unit of area, which is defined as "the area of a square with a side length of 1 kilometer" and also the unit for measuring land, abbreviated as km? .
