About Area Conversion

Area measures the two-dimensional space within a boundary, expressed in square units. It's essential for real estate, construction, agriculture, interior design, and land management. Whether you're buying property, planning a garden, calculating floor space, or measuring farmland, area conversions are a daily necessity in many professions and personal activities.

The metric system uses square meters and hectares, while the imperial system uses square feet and acres. Land measurements vary globally—the US uses acres, while most countries use hectares for agricultural and large land areas. Understanding both systems is essential when dealing with international real estate or reading property descriptions from different countries.

Our area converter supports all common units for both small spaces (like room dimensions) and large land areas (like farms and parks), giving you accurate conversions instantly.

Common Area Conversions

Area Unit Reference

Square Centimeter (cm²) – Used for small surfaces like paper dimensions, screen sizes, and electronic components. 1 cm² = 100 mm². Common in technical specifications and scientific measurements.

Square Meter (m²) – The SI unit for area and the global standard for room sizes, apartments, and construction projects. Also called a "centare" in some European countries. Floor plans and property listings worldwide use m².

Square Kilometer (km²) – Used for cities, countries, and geographic regions. 1 km² = 1,000,000 m² = 100 hectares. Used to measure everything from national parks to entire countries.

Hectare (ha) – Common metric unit for land area, especially in agriculture, forestry, and land management. 1 hectare = 10,000 m² = 100m × 100m. Easier to work with than km² for typical farm and property sizes.

Square Inch (in²) – Used for small areas in the US, like screen sizes (though often expressed as diagonal), material specifications, and engineering drawings. 1 in² = 6.452 cm².

Square Foot (ft²) – Primary unit for floor space and property size in the US, UK, Canada, and parts of Asia. Real estate listings, carpet measurements, and building codes typically use sq ft.

Square Yard (yd²) – Used for flooring, carpeting, and fabric in imperial countries. 1 yd² = 9 ft². Still common in the carpet and flooring industry.

Acre – Traditional land measurement unit with origins in medieval farming. 1 acre = 43,560 ft² ≈ 0.4047 ha. Originally defined as the area a yoke of oxen could plow in one day.

Square Mile (mi²) – Used for large land areas in the US and UK. 1 square mile = 640 acres = 2.59 km². A section of land in the US land survey system is exactly 1 square mile.
