- ▸Real estate — listings quote homes in km² in some countries and ha elsewhere; 291303 km² is the size buyers see in one market.
- ▸Land & farming — farmland is measured in acres in the US, hectares in Europe and India, and bigha in parts of South Asia.
- ▸Flooring & renovation — carpet and tile are sold in km² per unit, but room dimensions may be in ha.

Common mistakes
- ✕Squaring the linear factor only once — 1 m = 3.281 ft, but 1 m² = 10.764 ft² (factor squared).
- ✕Confusing acres with hectares (1 ha ≈ 2.471 acres).
- ✕The US survey acre differs slightly from the international acre. Land titles recorded using the US survey foot give an acre of about 4046.87261 m² — roughly 0.0004% larger than the international acre of 4046.8564224 m². On a single residential plot this is a few square centimetres. On a large ranch it can be several square metres, which is why legal descriptions state which foot was used.
Regional usage & source
