Where you'll actually use this
Area measures two-dimensional surface — the size of a floor, a country, or a piece of land. Metric uses square meters and hectares; imperial uses square feet and acres.
- Real estate
Apartment listings show square feet in the US, square meters in Europe, and tsubo or ping in parts of Asia.
- Farming & land
Farmland is sold in acres in North America and hectares in most of the rest of the world (1 ha ≈ 2.47 ac).
- Flooring & paint
Material coverage is often quoted per square meter or square foot — buy the wrong unit and you're off by an order of magnitude.
Common mistakes to avoid
- Squaring the linear factor
1 ft = 0.3048 m, so 1 ft² = 0.3048² ≈ 0.0929 m². Don't reuse the linear ratio.
- Hectare vs acre
A hectare is about 2.47 acres. Easy mix-up when comparing land listings across continents.
