Hectares to Acres
A hectare is 10,000 square meters, the standard unit for measuring farmland and forest area. An acre is 4,840 square yards, roughly the size of a football field, the traditional unit for land area in the US and UK. 1 ha equals ≈2.47105 ac, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to area, measured here against area's base unit (m²) — every other area unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
ac = ha × ≈2.47105
ha = ac × ≈0.404686
Worked example: 5 ha × ≈2.47105 = ≈12.3553 ac.
