Note

This result is a simplified model: it converts the single value you entered with the exact factors shown, and rounds to the display precision. It does not know your measurement's accuracy, and cooking or density conversions depend on how an ingredient is packed. Check critical figures against the original units.

Frequently asked questions

What is a hectare, exactly?+

A hectare is a metric unit of area equal to 10,000 square metres, or a square exactly 100 metres on each side. It's the standard unit for land area (farms, forests, plots) in most of the world outside the US.

How many acres are in a hectare?+

One hectare equals approximately 2.47105 acres. The relationship comes from the acre being defined as 4,046.8564224 square metres, so dividing 10,000 by that figure gives the conversion factor.

Why does an acre have such an oddly specific size in square metres?+

The acre is a historical English unit originally defined as the area a yoke of oxen could plough in a day, later standardized as 43,560 square feet — a figure that only converts to a 'clean' metric equivalent by coincidence of unit history, not design.

I'm comparing farm sizes between a US listing (acres) and a European one (hectares) — what's a quick sanity check?+

Roughly, 1 hectare is about 2.5 acres, so a 100-hectare farm is comparable to a 247-acre farm. Use this rough doubling-plus-a-bit as a sanity check against the calculator's precise figure.

Does this calculator handle acres to hectares as well as hectares to acres?+

Yes — entering a value in either field converts to the other using the same fixed ratio (1 hectare ≈ 2.47105 acres, so 1 acre ≈ 0.404686 hectares), so you can start from whichever unit you have.
