Area Converter — sq ft, sq m, Acres, Hectares & Indian Land Units
Area measurement comes up constantly in real estate, agriculture, construction, interior design, and geography — and almost every country uses different units. A property listing in the US is in square feet. The same property would be listed in square meters in Europe. Agricultural land in India is measured in bigha, kanal, or marla depending on the state. Farm land globally is described in acres or hectares. This free online area converter handles all of it — instantly converting between 23 area units including all major metric and imperial units, regional Indian land measurement units, and a room size calculator that computes area directly from room dimensions. Whether you are buying property, calculating flooring, understanding a land deed, or just trying to visualize how big a space is, this tool gives you all the answers in one place.

Metric Area Units
The square meter (m²) is the SI base unit for area — the area of a square with sides one meter long. Hectare (10,000 m²) and are (100 m²) are metric units used for land measurement. Square kilometer is used for geographic areas. The relationship between them is straightforward — all are powers-of-ten multiples of the square meter: 1 km² = 100 ha = 10,000 a = 1,000,000 m².
Imperial and US Area Units
An acre (4,046.86 m² or 43,560 sq ft) originated as the area a man and oxen could plow in one day. A square mile = 640 acres. A rood = ¼ acre. Square feet and square yards are standard in US and UK real estate. The key conversion anchors: 1 sq ft = 0.0929 m², 1 acre = 4,047 m², 1 sq mile = 2.59 km². One hectare equals approximately 2.47 acres — a useful cross-system reference for agriculture and land valuation.
Indian Land Measurement Units
India uses a rich variety of traditional land measurement units that vary significantly by state and region. Bigha is the most widely used but its size differs dramatically — from about 1,338 m² in West Bengal to 14,164 m² in Assam. Marla and kanal are standard in Punjab and Haryana. Guntha is used in Maharashtra and Karnataka. Ground is used in Tamil Nadu and Andhra Pradesh. Cent (1/100 of an acre) is used in Kerala and Tamil Nadu. For any official land transaction in India always verify the local definition with land records or a certified surveyor.
Real Estate Area Reference
In Indian real estate apartment sizes are quoted in square feet and sometimes in square meters. However buyers must clarify whether the quoted area is carpet area (actual usable space), built-up area (including walls), or super built-up area (including a share of common spaces). Super built-up area is typically 20–40% higher than carpet area — so a 1,000 sq ft super built-up apartment may have only 650–700 sq ft of actual living space. The Real Estate (Regulation and Development) Act (RERA) mandates disclosure in carpet area terms.
