What are square kilometers and hectares?
A square kilometer is one million square meters, used for large regions and cities. A hectare is 10,000 square meters (about 2.47 acres), the metric unit for land area. For scale: a tennis court is about 261 m² (2,808 ft²), and a soccer pitch is roughly 0.7 hectares.
How to convert square kilometers to hectares
1 km² = 100 ha. To convert, multiply the number of square kilometers by 100. For example, 5 km² = 500 ha, and 20 km² = 2,000 ha. To go the other way, multiply hectares by 0.01 (since 1 ha = 0.01 km²).
