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 are (100 m²) is primarily used in European land measurement. A small urban garden might be 2-5 ares, while a modest house plot could be 10 ares. Though less common today, it still appears in some property documents and agricultural contexts.
To convert between Square Kilometer (km²) and Are (a), use the following formulas:
1 Square Kilometer (km²) = 10000 Are (a)
1 Are (a) = 0.0001 Square Kilometer (km²)
1 km² = 1 * 10000 a = 10000 a
5 km² = 5 * 10000 a = 50000 a
10 km² = 10 * 10000 a = 100000 a
100 km² = 100 * 10000 a = 1000000 a
| Square Kilometer (km²) | Are (a) |
|---|---|
| 1 km² | 10000 a |
| 5 km² | 50000 a |
| 10 km² | 100000 a |
| 50 km² | 500000 a |
| 100 km² | 1000000 a |
