FAQs
How big is a hectare?
One hectare is 10,000 m² — equivalent to a square with 100 m sides. It is approximately 2.47 acres or about the size of a standard international football pitch (105 m × 68 m = 0.714 hectares). Farms, forests, and national parks are typically measured in hectares or square kilometres.
How big is an acre?
One acre is 4,047 m² or approximately 0.4 hectares. Historically it was defined as the area a man could plough in one day. A standard American football field (including end zones) is about 1.32 acres. British country estates are often described in acres.
How do I convert a floor plan from square feet to square metres?
Divide square feet by 10.764 to get square metres. For example, a 1,500 sq ft apartment is 1,500 ÷ 10.764 ≈ 139.4 m². Alternatively, multiply square feet by 0.0929. For a quick estimate, divide by 10 and subtract 5% — close enough for most purposes.
