Accuracy
Accuracy and assumptions
All figures use the international definitions of both units, so the conversion is identical in every country. Table values are shown to six significant figures — the same precision as the published conversion factors. Neither unit varies by region or by the type of land being measured, so these numbers do not need adjusting for local practice.
Key facts
Key facts worth knowing
- 1 hectare is exactly 10,000 square metres — a square measuring 100 m on each side.
- 1 acre is exactly 4,046.8564224 square metres, or 43,560 square feet.
- 100 hectares equals 1 square kilometre; 640 acres equals 1 square mile.
- 1 hectare is roughly 1.4 football pitches. A US football field including end zones is about 0.54 hectares.
- The conversion has been fixed since the 1959 international yard and pound agreement — it does not change over time.
If any of that needs unpacking, we cover what a hectare actually is, where the acre came from, and how many football pitches fit in a hectare in more depth. For the wider picture, see which countries use hectares and which use acres, or the FAQ hub for short answers.

FAQ
Questions about these conversions
100 hectares equals 247.105 acres. The calculation is 100 × 2.47105. For context, 100 hectares is exactly one square kilometre — a substantial commercial farm, or roughly 140 football pitches of land.
5 acres equals 2.02343 hectares. The calculation is 5 × 0.404686. That is a common size for a rural homestead or smallholding, and works out to roughly three football pitches.
1,000 hectares equals 2,471.05 acres. That is 10 square kilometres of land — the scale of a large estate, plantation or nature reserve rather than an individual farm.
20 acres equals about 8.0937 hectares. The calculation is 20 × 0.404686. Twenty acres is a typical size for a small working farm or a large rural property in the United States.
Yes. Both the hectare and the international acre have exact legal definitions in square metres, so 1 hectare is 2.47105 acres in every country. Unlike some historical units, neither varies by region, by year, or by the type of land.
