Acres to hectares
Land measured in acres — an American farm, a British estate, a Canadian lot — often has to be reported in hectares for official, scientific or international purposes. One acre is 4 046.86 square meters, which makes it 0.404686 hectare. Multiply acres by 0.404686, or divide by 2.47105.
Rule of thumb
Take 40 % of the acres: 50 acres ≈ 20 ha (20.2 exactly), 250 acres ≈ 100 ha (101.2). It undershoots by about 1 %, which is fine for a first look at a listing.
- 1 acre = 0.4 ha
- 2.5 acres = 1.01 ha (almost exactly one hectare)
- 5 acres = 2.02 ha
- 10 acres = 4.05 ha
- 40 acres = 16.19 ha
- 100 acres = 40.47 ha
- 640 acres = 259 ha (one square mile)
- 1000 acres = 404.69 ha
History in the number
The acre was the area a yoke of oxen could plough in a day: one furlong long by one chain wide, 660 ft × 66 ft. The hectare was defined in 1795 as a neat 100 m × 100 m square. That is why the conversion factor is an awkward decimal — the two units come from different worlds.
Practical notes
Farming. Seeding and fertiliser rates on North American product labels are per acre; European labels are per hectare. Multiply a per-acre rate by 2.47 to get the per-hectare rate. Real estate. A "10-acre property" abroad is a 4-hectare property. Forestry and conservation. International reports (FAO, UNEP) always use hectares, so US figures are converted before publication.
