Common questions
How big is an acre visually?
About 75% of a US football field, or a square roughly 208.7 feet (63.6 m) on a side.
Why do home listings use square feet in the US but square meters almost everywhere else?
Custom. The math is fixed: 1 m² = 10.7639 sq ft, so a 100 m² apartment is 1076 sq ft.
Is a hectare bigger than an acre?
Yes — one hectare equals about 2.471 acres. Sixty-two hectares is roughly one square mile.
