Use SI areas: 1 ha = 104 m2 and 1 acre = 4,046.8564224 m2. Hence:
1 acre = 4,046.8564224 / 10,000 ha = 0.40468564224 ha
For any area A (in acres):
Aha = Aacre × 0.40468564224
Inverse rule:
Aacre = Aha ÷ 0.40468564224 ≈ Aha × 2.47105381
One acre is equal to 0.40468564224 hectares. This is based on the exact metric relationship where 1 acre = 4,046.8564224 square meters and 1 hectare = 10,000 square meters.
To convert acres to hectares, multiply the area value in acres by 0.40468564224. The formula is: Area (ha) = Area (acres) × 0.40468564224.
Converting acres to hectares is crucial in agriculture, land management, and environmental studies where metric units are required. It ensures consistency and comparability in international data and scientific reporting.
