Hectare to Acre Conversion

Metric meets imperial: the two big land units of official records, converted precisely.

1 Hectare = 2.4711 Acres · 1 Acre = 0.4047 Hectares

The hectare and the acre are the two units in which serious land — farms, estates, government allocations — is measured worldwide. The hectare is metric: exactly 10,000 square meters, the area of a 100 m × 100 m square. The acre is imperial: exactly 43,560 square feet. One hectare equals about 2.47 acres, and one acre is about 0.405 hectares.

In India and Nepal both appear constantly: official digitized records and agricultural statistics use hectares, while older deeds, real-estate listings, and everyday speech lean on acres (and regional units like the bigha). A useful mental shortcut is "hectares × 2.5, minus a little" — 4 hectares ≈ 10 acres is accurate to within about 1%.

The formula

Acres = Hectares × 2.47105

Hectares = Acres × 0.404686

Exactly: 1 hectare = 10,000 m² = 107,639.1 sq ft; 1 acre = 4,046.86 m²

Worked examples

Example 1 — a 3.2 hectare farm record

An agricultural record of 3.2 hectares converts to 3.2 × 2.47105 = 7.91 acres. Listed for sale "per acre", the farm should be advertised as just under 8 acres.

Example 2 — buying 12 acres, registering in hectares

A 12-acre purchase registers as 12 × 0.404686 = 4.856 hectares in a metric land registry. Rounding to 4.86 ha keeps the record accurate to a few square meters.

Good to know

The hectare is not an SI unit itself but is accepted for use with the SI, and it is the standard unit of agricultural statistics almost everywhere — including India's and Nepal's agriculture ministries. The "are" (100 m², from which "hect-are" derives) still appears in some older European and Nepali records; our converter supports it directly.
