What is a hectare, and how big is it?
A hectare is the metric unit of land area: 10,000square meters, the area of a square 100 meters on each side. Nearly every country outside the United States quotes farmland, forests and property in hectares, so if you’re reading an international listing, a crop report or a Canadian land registry, hectares are what you’ll see.
For a mental picture: one hectare is about 1.87 American football fields (including end zones), while one acre is about 0.76of a field. If you think in acres, a hectare is “two and a half acres, less a bit” — the exact factor is 2.4711.
