When to Convert Acres & Hectares

Agricultural Records

Convert farm land between acres (used in rural India) and hectares (government records).

Bank & Loan Docs

Farm loan documents and crop insurance often require land area in both acres and hectares.

International Comparison

Compare land prices between Indian properties (acres) and European listings (hectares).

Environmental Projects

Forest coverage, solar farm areas and conservation projects report in both units.

Urban Planning

Township and layout plans often mix acres (local standard) with hectares (official metric).

Academic & Research

Research papers on land use and agriculture need consistent conversion across datasets.

Acre & Hectare Questions

1 acre = 0.40468564224 hectares exactly. A quick approximation: 1 acre ≈ 0.4 ha. Conversely, 1 hectare = 2.47105 acres.

1 hectare = a 100 m × 100 m square. It is roughly 1.5× the size of a standard football pitch (68 m × 105 m ≈ 0.71 ha). A typical sports stadium occupies 2–5 hectares of land.

India officially adopted the metric system, so government records (land records, forest surveys, census data) use hectares. However, "acre" persists in everyday usage, particularly in agriculture and urban real estate in many states.

1 sq km = 100 hectares = 247.105 acres. So a city block of 1 sq km contains about 247 acres of land.

1 hectare = 2.47105 acres × 1.6 bighas/acre = 3.954 bighas (North Indian pucca bigha). Approximately, 4 bighas ≈ 1 hectare. Use our Bigha to Acre converter for detailed bigha conversions.
