Convert hectares to acres — and back — with the exact factor (1 ha = 2.4710538 ac, from the two units’ exact square-meter definitions). Loads with ha → ac preselected.
The formula
acres = hectares × 2.4710538 · hectares = acres × 0.40468564. Mental math: two and a half acres per hectare, minus a hair — 40 ha → ~99 acres (true 98.8).

Farms, plots, price-per-unit
Agriculture runs on hectares in most of the world and acres in the US — subsidy documents, yield figures (bushels/acre vs tonnes/ha), and farm sales all cross this line. Building plots: a quarter-acre suburban lot is 0.101 ha ≈ 1,012 m²; a “half-hectare block” is 1.24 acres. The FAQ’s visual anchors (hectare ≈ rugby pitch, acre ≈ 60% of a football pitch) make listing sizes concrete. House-scale floor areas belong one step down, in the square meters to square feet converter.
