Hectares to Acres: Frequently Asked Questions

A hectare is about two and a half times bigger than an acre. One hectare equals 2.47105 acres, so picturing two and a half acres side by side gets you close to a single hectare. In metric terms a hectare is a 100 m × 100 m square covering 10,000 square metres.

A hectare is roughly 147% larger than an acre, since 2.47105 acres fit inside one. For a visual sense of scale: one hectare is about 1.4 football pitches, while a single acre is closer to 0.6 of one. A hectare covers 10,000 m²; an acre covers 4,046.86 m².

A hectares to acres conversion changes a land area measured in metric hectares into imperial acres. You multiply the hectare figure by 2.47105 to get acres. It is the standard calculation for comparing international property listings, farm sizes and survey data between metric and imperial countries.

There are 2.47105 acres in one hectare. Rounded for everyday use that is about 2.47 acres, or roughly two and a half. To convert any hectare figure, multiply it by 2.47105. For example, 10 hectares equals 24.7105 acres and 100 hectares equals 247.105 acres.

Multiply the number of acres by 0.404686 to get hectares. For example, 5 acres × 0.404686 = 2.02343 hectares. You can also divide the acre figure by 2.47105 for the same result. Enter any value in the calculator above and it converts instantly as you type.

Multiply by 0.404686, not by 2.47105. Land at 40,000 per hectare is 40,000 × 0.404686 = 16,187.44 per acre. Rates per unit of area convert in the opposite direction to areas themselves, because an acre is the smaller unit — the same land costs less per acre than per hectare.

Multiply by 0.404686. A wheat crop of 8.5 tonnes per hectare is 3.43983 tonnes per acre. The same factor applies to seed rates, fertiliser rates and stocking densities. Multiplying by 2.47105 instead gives figures roughly two and a half times too high, and the result still looks like a plausible yield, which is what makes the error hard to spot.

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.

Almost all of them. The hectare is standard across the EU, India, China, Brazil, Australia and most of Africa and Asia. The United States uses acres widely, and the United Kingdom still uses them informally despite officially adopting the hectare.

The acre predates the metric system. It originally described the area a yoke of oxen could plough in a day — one furlong by one chain. When it was standardised against the metre in 1959, that historical size became 4,046.8564224 m² exactly.

Only for presentation. Use 2.47105 for everyday work — it is accurate to within a fraction of a square metre per hectare. This calculator works at full precision internally and rounds only when displaying, so repeated conversions never drift.
