About Area Units

Area measures two-dimensional space. The SI unit is the square metre (m²). Land is commonly measured in acres (imperial) or hectares (metric) — 1 hectare = 10,000 m², 1 acre ≈ 4,047 m². In India, bigha and ground are traditional units that vary by state. Real estate listings often mix sq ft (US/India) with m² (Europe).
