Picturing a hectare

A hectare is a square 100 m on each side, about 328 × 328 ft. A full-size football (soccer) pitch at the recommended 105 × 68 m covers 0.714 ha, so a hectare is about 1.4 pitches. One square kilometer is 100 hectares, and a square mile is 259 hectares.

The quick rule is 'a hectare is about two and a half acres'. That's 1.2% high, close enough to picture a farm's size from a listing. For valuation or land-tax purposes, use the exact factor, since 1.2% of a large farm is a meaningful area.

Farmland, forestry and land listings

Farm sizes, crop yields and forest statistics outside the US are reported in hectares. A 200 ha farm is 494 acres. Yields per area need converting too. A yield per hectare becomes a yield per acre when you divide by 2.471, because each acre is smaller. Mixing per-hectare and per-acre rates is a common source of large errors.

For small plots under a hectare, square meters or square feet are usually clearer. 0.25 ha is 2,500 m², or 26,910 sq ft. To calculate an area from measurements before converting, the square footage calculator works in feet or meters.

Frequently asked questions

Which is bigger, a hectare or an acre?

A hectare is bigger, about 2.47 times the size of an acre. An acre is 0.4047 ha, a little over 40% of a hectare. So the number of acres is always larger than the number of hectares for the same piece of land. If you get the opposite, the factor was applied the wrong way.

How do I convert a price per hectare to a price per acre?

Divide the price per hectare by 2.471, because an acre is smaller than a hectare. Land priced at 10,000 per hectare costs about 4,047 per acre in the same currency. To go from per acre to per hectare, multiply by 2.471.

Where does the word hectare come from?

It combines the metric prefix 'hecto' (100) with the 'are', a 10 × 10 m unit of 100 m² from the original French metric system. So a hectare is 100 ares, or 10,000 m². The are itself is rarely used today, but the hectare is accepted for use with the SI and is the standard land unit in most countries.
