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.

Did you know?

A football pitch ≈ 0.7 ha

A standard FIFA pitch is roughly 7,000 m² — a handy mental shortcut for hectare estimates.
