Area Converter

Area measures two-dimensional space — the extent of a surface. The SI unit is the square meter (m²), defined as the area of a square with 1-meter sides. This converter handles metric area units (square meter, square kilometer, square centimeter, hectare = 10,000 m²), imperial units (square foot, square yard, square inch, square mile, acre = 43,560 ft²), and regional units (rai for Thailand = 1,600 m², dunam for Middle East = 1,000 m²). The hectare and acre are the most-used land units globally, with 1 hectare ≈ 2.471 acres. Use area conversion for real estate listings, agricultural land sizing, construction projects, geographic and demographic studies, and engineering. The square meter is the international standard, but the square foot dominates American real estate, and the acre remains entrenched in American and British property records.

The square meter is the standard metric area unit for room sizes, real estate, and small property measurements.

The square kilometer measures cities, national parks, and large geographic regions in metric countries.

The square centimeter is used in engineering tolerances, biology specimen measurements, and small-area calculations.

The square millimeter is the precision area unit for electronics, microfabrication, and component cross-sections.

The hectare equals 10,000 square meters and is the international standard for agricultural land and forestry.

The acre is the standard unit for American and British farmland, real estate, and recreational property.

The square foot is the standard unit for American and British residential and commercial real estate listings.

The square inch measures American printer paper coverage, manufacturing tolerances, and small surface areas.

The square yard measures American carpet, fabric, and small landscaping projects in everyday commerce.

The square mile measures American counties, large parks, and geographic regions in everyday US contexts.

The rai is the traditional Thai land unit, equal to 1,600 square meters, used in real estate and agriculture.

The dunam is the historical Middle Eastern land unit, equal to 1,000 square meters, used in regional property records.

• ✓1 hectare (10,000 m²) is about the size of a rugby pitch or 2.5 soccer fields. Most European farmland is measured in hectares.
• ✓1 acre ≈ 0.405 hectares. The US and UK measure rural land in acres.
• ✓European apartments are advertised in m², US homes in ft². 100 m² ≈ 1076 ft².
• ✓Always distinguish land area (horizontal) from floor area (interior). Property listings often refer to either.

• ✗Confusing linear units (m) with area units (m²). 20 m is a length; 20 m² is an area.
• ✗Mixing acres and hectares in agricultural contracts — acres are 40% smaller.
• ✗Reading "sq ft" in a US listing as "ft" — a 100 ft² closet is 10 m², not 100 m².
• ✗Using US and UK fluid units on area — no relation, different dimensions.
