The square mile (mi²) measures large territories like cities and counties. New York City covers 302.6 mi², while London spans approximately 607 mi². This unit is used in urban planning, geography, and environmental management. 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 Mile (mi²) and Are (a), use the following formulas:
1 Square Mile (mi²) = 25899.88 Are (a)
1 Are (a) = 0.00003861021749907722 Square Mile (mi²)
1 mi² = 1 * 25899.88 a = 25899.88 a
5 mi² = 5 * 25899.88 a = 129499.40000000001 a
10 mi² = 10 * 25899.88 a = 258998.80000000002 a
100 mi² = 100 * 25899.88 a = 2589988 a
