Frequently Asked Questions

One acre equals 4,046.856 square meters. An acre was historically defined as the area that could be ploughed in one day with a yoke of oxen. It is used primarily in the US, UK, and other countries for measuring land.

A hectare is a metric unit of area equal to 10,000 square meters (100m × 100m) or 2.471 acres. It is the most commonly used unit for measuring land areas internationally and in agriculture. One square kilometer equals 100 hectares.

One square meter equals 10.7639 square feet. Square feet are widely used in the United States and UK for measuring floor space and real estate. Square meters are used in most other countries.

There are exactly 640 acres in a square mile. A square mile is 1 mile × 1 mile = 2.58999 km². Sections of land in the US Public Land Survey System are each 1 square mile, divided into 640 one-acre plots.

Multiply square meters by 10.7639 to get square feet. For a quick estimate, multiply by 10.75. For example, a 50 m² apartment ≈ 538 sq ft. To go the other way, multiply square feet by 0.0929 to get square meters.

An acre is 43,560 square feet or 4,046.86 square meters. Historically it was defined as the area a yoke of oxen could plough in a day. A standard American football field (including end zones) is about 1.32 acres. One acre is roughly the size of a city block in many US cities.

A hectare = 10,000 m², while an acre = 4,046.86 m². One hectare equals approximately 2.471 acres. Hectares are the international standard for measuring land and are used by the UN for agricultural statistics. Acres are mainly used in the US, UK, and countries with British measurement heritage.

For a rectangular room, multiply length × width in the same units to get area. For example, a room 5 m × 4 m = 20 m². For irregular rooms, break them into rectangles, calculate each, and add them up. Always measure in consistent units before converting.

Bigha and katha are traditional South Asian land area units that vary by region. In Bangladesh, 1 bigha = 1,338 m² and 1 katha = 66.89 m² (20 katha = 1 bigha). In India, values differ by state — a bigha in West Bengal is different from one in Rajasthan. These units are still widely used in rural land transactions.

A square yard = 9 square feet = 0.8361 m². It is used primarily in the US and UK for carpet, flooring, fabric, and some construction materials. When buying carpet or turf, prices are often quoted per square yard. One square yard equals 3 feet × 3 feet.

Comparing Property Prices Across Countries: Why "$500/sqft vs €4,500/sqm" Isn't What It Looks Like

Comparing Property Prices Across Countries: Why "$500/sqft vs €4,500/sqm" Isn't What It Looks Like

"$500 per square foot" and "€4,500 per square meter" might represent nearly identical value — but a naive comparison without converting units first could make one market look 9x more expensive than it actually is. Here's the two-step conversion (area units, then currency) needed for valid international price-per-area comparisons, why GIA/NIA definitional differences compound with unit conversion, and why land-area and floor-area price comparisons answer different questions entirely.
